[easwars]

Use rlspb for messages and rlsgrpc for services

RELEASE NOTES: n/a

Will this conflict with your current RLS PRs? If so I don't know if this is worth doing now; let's just do it as part of that work. But if this file isn't changing, then this is fine to do now.

Are there no test changes needed? That would be surprising.

Actually, I have created a new file control_channel.go which contains the control channel functionality. So, this file will eventually be deleted. But I like having the double import in there as just a visual re-enforcement to remind me to do that everytime :)

We currently only have a unit test which tests the rlsClient type. So, the test doesn't currently bring up any RLS service. So, it was not affected.

This is a test coverage gap for now, then.

Please make sure that one does the double-import too!
