Refactor node upgrade to include less serial tasks
This commit moves the pulling of images, packages,
and updating config files into a non-serialized play.
The serialized play is now in charge of marking unschedulable,
draining, stopping and restarting services, and marking
schedulable.
If rpm install / container download takes 60s per host,
this will save 3 hours and 10 minutes at 200 hosts per cluster
and forks of 20 hosts.
