Make awx/main/tests/live dramatically faster

[AlanCoding]

SUMMARY

I noticed a lot of slowdown running the "live" tests, particularly related to projects which do a lot of syncing and running of jobs. When I cross-referenced against the UI I saw a lot of things hanging out in "pending" status. That's strange... even stranger that they wind up passing.

Turns out, when "pytest" is in sys.argv we just don't send any messages to pg_notify. Well there's you're slowdown! To do anything, the tests were waiting for the once-ever-20-seconds periodic task.

• before: 5 passed, 5 warnings in 167.92s (0:02:47)
• after: 1 failed, 4 passed, 5 warnings in 17.58s (think the failure is a local problem)

That 17 seconds is 😚

This is still not implemented in the separate dispatcher library. I still haven't dived into the details, but having this as a dispatcher config-like property is probably the best path forward, so this patch should help make changes in that area as well.

We may still have friction in some other checks, because this is going to move us in the direction of sending messages by default (which will error if not configured right). While this is more risky for development, I consider it less risky for production purposes.
