rosstimothy 550d23d15d Fix goroutine and memory leak in watchCertAuthorities (#10871)
* Fix goroutine and memory leak in watchCertAuthorities

The CA Watcher was blocking both on writing to a channel when the watcher
was closed and on HTTP calls that had no request timeout or context passed
to cause cancellation.

All resourceWatcher implementations that had a bug which may cause them to block
on writing to a channel forever were fixed by selecting on the write and ctx.Done.

Adding context.Context to all Get/Put/Post/Delete methods on the auth HTTPClient to
force callers to propagate context. Prior all calls used context.TODO which
prevents requests from being properly cancelled.

Add context propagation to RotateCertAuthority, RotateExternalCertAuthority,
GetCertAuthority, GetCertAuthorities. This is needed to get the correct ctx
from the CertAtuhorityWatcher all the way down to the HTTPClient that makes
the call.

Closes #10648
