Removes the gRPC channel if an exception occurs while instantiating the client

Includes also other minor changes to gRPC channel creation/connection
process, such as:
- More compact logs showing the gRPC client key
- GrpcChannelController.connectChannel() now returns the same
 StatusRuntime exception, no need to wrap it in an IOException
- Wait for channel shutdown after initial connection error
