Adds `UpsertCertAuthority` to the `teleport.v1.trust.TrustService`
and deprecates the HTTP api. The `services.Trust` interface was
also updated to include a `context.Context` in both
`CreateCertAuthority` and `UpsertCertAuthority.
To ensure backwards compatibility the `auth.Client` will first
attempt to use the gRPC client and if that fails with a not
implemented error it will fallback to using HTTP.
Part of #6394
Adds `DeleteCertAuthority` to the trust grpc service and deprecates
the legacy HTTP api. Additionally the `DeleteCertAuthority` method
in the `services.Trust` interface now takes a `context.Context` as
the first parameter. In order to plumb the context through from all
the call sites `DeleteRemoteCluster` from `services.Presence` was
also modified to take a `context.Context` as the first parameter.
The Okta service and client have been introduced. This will allow for the
maintenance of Okta objects via our gRPC server and auth client. Some
additional improvements have been made so that the local okta service now
better reflects the gRPC definition.
Additionally, the gRPC authorization mechanism has been lifted out of
`lib/auth/grpcserver.go` and moved into a common authorizer. Finally, the
ability to check access to verbs has been lifted out of the `pluginsv1`
service into that same authorizer. This will hopefully provide a good base
for separate gRPC services in the future.
Adds a new `GetCertAuthorities` unary RPC to
`teleport.v1.trust.TrustService` and deprecates the equivalent
HTTP endpoint. All associated interfaces have been updated to remove
the marshal options as well.
The HTTP client created by `auth.NewClient` has an idle timeout of
30s and each instance periodically gets cert authorities in
`TeleportProcess.syncRotationStateCycle`. If there has been no
activity when the ticker expires then the request will result in a
brand new connection to Auth to be established. This can cause a
spikes in open file descriptors on the Proxy when there are a large
number of instances connected via a tunnel.
To prevent periodic dialing when retrieving cert authorities the
endpoint has been migrated to the new Trust gRPC service. For now
only the get endpoint has been migrated but the rest of the CRUD
operations for cert authorities should be migrated from the HTTP
api to the gRPC service as well.
