* 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.
Kube
This PR fixes the inheritance of `kubernetes_resources` from the user's roles when the user has active access requests to a `kube_cluster`.
If the user had an active request to a `kube_cluster`, Teleport ignored the role's `kubernetes_resources` and returned an empty set for the allowed and denied pods. This resulted in the user being unable to see any pods in the cluster.

This PR introduces a gRPC service to retrieve the pods available using the `search_as_roles` configured in the user's roles.
This gRPC service receives a TLS identity and manipulates it to access the Teleport Kubernetes Proxy and retrieve the pods available for a hypothetical user that has the `search_as_roles` defined for its roles.
The response does not leak the certificate nor the pod details other than `name`, `namespace` and `labels`.
