Subject: [PATCH] Start task RPC service before waiting

If the TaskServer RPC service is not started before the launcher waits
for its completion, then on shutdown it could result in a hang:

WARNING oslo_messaging.server Possible hang: stop is waiting for start to complete

This is a port of the fix for Sahara bug #1546119.
