* Move the authorizer into its own package.
The Authorizer and associated functions and constants have been moved into
their own package `authz`. This will allow us to more easily create separate
services for gRPC functionality so that we're not pushing as much into the
`lib/auth` package.
Though this PR is large, the only actual code change here is making
`ContextForLocalUser` exported and changing the `permissions_test.go` so that
it doesn't rely on the `lib/auth` package.
* Use context functions.
* Test and linting fixes.
* Add in a temporary alias file to ensure e still compiles.
* Use functions instead of var aliases for performance reasons.
* Adding in godocs, cleaning up tests.
* Fix tests.
* Add a few more aliases.
Improve UserMetadata audit logging by using `tlsca.Identity.GetUserMetadata()`
more consistently in audit logs.
There are still a handful of logs that don't include the data above for lack of
context (in the general sense and in the Go context sense), but many more
entries now call back to identity in some way.

Update metalinter, fix a few lint warnings and replace deprecated linters.
`deadcode`, `structcheck` and `varcheck` are abandoned and now replaced by [`unused`][1].
Since 1.19, `go fmt` reformats godocs according to https://go.dev/doc/comment. I've done a bulk-reformatting of the codebase to keep the linter happy. Backporting is mostly harmless (the exception being `lib/services/role_test.go`, that for some reason breaks the _old_ linter using the new format).

Implement passwordless cluster settings, as described by RFD 52: Passwordless
[1]. See https://github.com/gravitational/teleport/pull/11716 for recent RFD
changes.
Add the "passwordless" connector and allows cluster admins to configure it as
the cluster default.
teleport.yaml:
```yaml
auth_service:
authentication:
type: local
second_factor: on
webauthn:
rp_id: example.com
passwordless: true # enables/disables passwordless
connector_name: passwordless # sets passwordless as the default
```
`tsh` obeys the connector name if present. User overrides are possible via `tsh
--auth=local` or `tsh --auth=passwordless`. The `tsh --pwdless` flag is now
removed, as discussed in recent RFD changes.
Web API `/ping` and `/ping/{connector}` endpoints are changed to support
"passwordless" and to provide other necessary information.
#9160
[1] https://github.com/gravitational/teleport/blob/master/rfd/0052-passwordless.md#cluster-settings
* Add passwordless toggle to AuthPreferenceSpecV2 proto
* Update generate protos
* Add AuthPreference fields and validation
* Reserve system connector names
* Distinguish between type=local and local connector
* Add passwordless option to teleport.yaml
* Do /ping and /ping/{connector} changes
* Make tsh respect the passwordless connector, remove --pwdless
* Add certificate renewal bot
This adds a new `tbot` tool to continuously renew a set of
certificates after registering with a Teleport cluster using a
similar process to standard node joining.
This makes some modifications to user certificate generation to allow
for certificates that can be renewed beyond their original TTL, and
exposes new gRPC endpoints:
* `CreateBotJoinToken` creates a join token for a bot user
* `GenerateInitialRenewableUserCerts` exchanges a token for a set of
certificates with a new `renewable` flag set
A new `tctl` command, `tctl bots add`, creates a bot user and calls
`CreateBotJoinToken` to issue a token. A bot instance can then be
started using a provided command.
* Cert bot refactoring pass
* Use role requests to split renewable certs from end-user certs
* Add bot configuration file
* Use `teleport.dev/bot` label
* Remove `impersonator` flag on initial bot certs
* Remove unnecessary `renew` package
* Misc other cleanup
* Do not pass through `renewable` flag when role requests are set
This adds additional restrictions on when a certificate's `renewable`
flag is carried over to a new certificate. In particular, it now also
denies the flag when either role requests are present, or the
`disallowReissue` flag has been previously set.
In practice `disallow-reissue` would have prevented any undesired
behavior but this improves consistency and resolves a TODO.
* Various tbot UX improvements; render SSH config
* Fully flesh out config template rendering
* Fix rendering for SSH configuration templates
* Added `String()` impls for destination types
* Improve certificate renewal logging; show more detail
* Properly fall back to default (all) roles
* Add mode hints for files
* Add/update copyright headers
* Add stubs for tbot init and watch commands
* Add gRPC endpoints for managing bots
* Add `CreateBot`, `DeleteBot`, and `GetBotUsers` gRPC endpoints
* Replace `tctl bot (add|rm|ls)` implementations with gRPC calls
* Define a few new constants, `DefaultBotJoinTTL`, `BotLabel`,
`BotGenerationLabel`
* Fix outdated destination flag in example tbot command
* Bugfix pass for demo
* Fixed a few nil pointer derefs when using config from CLI args
* Properly create destination if `--destination-dir` flag is used
* Remove improper default on CLI flag
* `DestinationConfig` is now a list of pointers
* Address first wave of review feedback
Fixes the majority of smaller issues caught by reviewers, thanks all!
* Add doc comments for bot.go functions
* Return the token TTL from CreateBot
* Split initial user cert issuance from `generateUserCerts()`
Issuing initial renewable certificate ended up requiring a lot of
hacks to skip checks that prevented anonymous bots from getting
certs even though we'd verified their identity elsewhere (via token).
This reverts all those hacks and splits initial bot cert logic into a
dedicated `generateInitialRenewableUserCerts()` function which should
make the whole process much easier to follow.
* Set bot traits to silence log messages
* tbot log message consistency pass
* Resolve lints
* Add config tests
* Remove CreateBotJoinToken endpoint
Users should instead use the CreateBot/DeleteBot endpoints.
* Create a fresh private key for every impersonated identity renewal
* Hide `config` subcommand
* Rename bot label prefix to `teleport.internal/`
* Use types.NewRole() to create bot roles
* Clean up error handling in custom YAML unmarshallers

* Fix some review comments
* Add renewable certificate generation checks (#10098)
* Add renewable certificate generation checks
This adds a new validation check for renewable certificates that
maintains a renewal counter as both a certificate extension and a
user label. This counter is used to ensure only a single certificate
lineage can exist: for example, if a renewable certificate is stolen,
only one copy of the certificate can be renewed as the generation
counter will not match
When renewing a certificate, first the generation counter presented
by the user (via their TLS identity) is compared to a value stored
with the associated user (in a new `teleport.dev/bot-generation`
label field). If they aren't equal, the renewal attempt fails.
Otherwise, the generation counter is incremented by 1, stored to the
database using a `CompareAndSwap()` to ensure atomicity, and set on
the generated certificate for use in future renewals.
* Add unit tests for the generation counter
This adds new unit tests to exercise the generation counter checks.
Additionally, it fixes two other renewable cert tests that were
failing.
* Remove certRequestGeneration() function
* Emit audit event when cert generations don't match
* Fully implement `tctl bots lock`
* Show bot name in `tctl bots ls`
* Lock bots when a cert generation mismatch is found
* Make CompareFailed respones from validateGenerationLabel() more actionable
* Update lib/services/local/users.go

Fixes#5352
```yaml
allow:
impersonate:
users: ['alice', 'bob']
roles: ['*']
where: 'contains(user.spec.traits["groups"], impersonate_role.traits)'
```
Adds "impersonator" to all X.509 and SSH client certs
issued using impersonation and does best effort to track
requests by impersonators in audit events.
Limits certs TTL to the impersonator's max session TTL.
Prevents impersonating users to recursively impersonate
other users.
Allows impersonating users to renew their own certificate,
for example to set route to cluster.
Adds missing token permission for editor role.
This commit introduces GRPC API for streaming sessions.
It adds structured events and sync streaming
that avoids storing events on disk.
You can find design in rfd/0002-streaming.md RFD.
* Check if user exists before creating/updating to return clearer error message
* Remove unnecessary checking if user exists before creating
* When creating user, set CreatedBy if not set by original caller
Our auth middleware already attaches a TLS identity as context value.
Plumb contexts through and extract the username when recording events.
If the received context doesn't have an identity attached, use "system"
as username.
Lots of noise here due to missing context.Context plumbing :(
We should eventually plumb contexts to all those RPC interfaces.
