Bernard Cafarelli dc68b69fc0 Re-use existing ProcessLauncher from wsgi in RPC workers
If both are run under the same process, and api_workers >= 2, the server
process will instantiate two oslo_service.ProcessLauncher instances

This should be avoided [0], and indeed causes issues on subprocess and
signal handling: killed RPC workers not respawning, SIGHUP on master
process leading to unresponsive server, signal not properly sent to all
child processes, ...

To avoid this, use the wsgi ProcessLauncher instance if it exists
