* refactor(worker): Move tcp_proxy into its own package
This refactors:
- the tcp_proxy.go into worker/proxy/tcp
- add a missing unit test for the HandleTcpProxyV1
- refactors session.go into worker/session, needed to avoid import cycle
- adds a baseline for a mock controller session client
- go lint fixes
* Add sleep between spinning listener goroutine and dialing

Go's TLS stack doesn't need a separate CA cert and in fact for sessions
we don't use this. So simplify the worker connection to remove an
unnecessary extra key generation.
* Possible api changes.
* Worker API update.
* Updating import alias name.
* Moving session down a level as a member of the GetSessionResponse.
* Marshal the auth flag into the GetSessionResponse proto instead of the session.
