* Emit new `AgentMetadataEvent`
Part of https://github.com/gravitational/cloud/issues/3550.
This commits adds a new `UpstreamInventoryAgentMetadata` that is sent
from a Teleport agent to an auth server.
Once received, it is transformed into an `AgentMetadataEvent` and sent
to PreHog.
Most `UpstreamInventoryAgentMetadata` fields are intentionally kept as
empty in this PR. Follow up PRs will be opened with the mechanisms
required to fill them (as described in #21337).

* Add missing import
* Handle error
* Revert "Spawn gorountine that fetches metadata on each new stream"
This reverts commit fe4f2790be.
* Send agent metadata to auth server once per stream
* Improve note about agentMetadataDone
* Don't process command output & file content on the agent
Since agents cannot be trusted, regex validation and sanitization should
happen in PreHog anyways. So this commit removes such logic in favor of
moving it to PreHog.

Instance heartbeats have caused significant etcd instability in
larger clusters. This makes the instance heartbeat a noop unless
the `TELEPORT_UNSTABLE_ENABLE_INSTANCE_HB` is explicitly set.
This allows for us to keep the instance heartbeats to continue to
test and determine the underlying problem without rolling back the
entire feature, while also preventing it from imapcting users.
This reverts commit 4f3aa9a3f2.
We're unable to build for 32-bit Linux due to
https://github.com/golang/go/issues/55152,
which looks like it will be fixed with Go 1.19.2 next week.
We'll re-evaluate with the next Go release and reintroduce this change
as soon as we can.
* Add Yubikey PrivateKey implementation for use by Teleport clients.
- Add yubikey login logic, reusing previously stored private keys.
- Fix identity file decoding with PIV keys, which sign ecdsa certificates.
- Add libpcsclite-dev pre-req for building on linux.
- Remove unnecessary keys.Signer interface and move its functionality to keys.PrivateKey.
- Move retry and jitter utils to new api/utils/retryutils package.
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).
