broadcast: transition stream to live

[Saxon Milton]

Now that we have broadcast and stream configuration functionality in place, we need to problematically switch the broadcast to “live mode”. From this stack overflow feed, it’s suggested the correct process is this:

1. ensure you have broadcast and livestream created and ready.
   and ensure that broadcast lifecycle status is not COMPLETE, otherwise recreate broadcast ... so ensure that your broadcast lifecycle status is ready
2. bind broadcast to livestream
3. start publishing video to livestream
4. wait for livestream status active
5. transition to testing (yes, you have to do it instead of moving to live)
6. wait for broadcast lifeCycleStatus to become testing
7. transition to live
8. wait for broadcast lifeCycleStatus to become live
