Making Resync a blocked operation for the PodMonitor (master)

[mheese]

This will make Resync() a blocked operation for the PodMonitor as discussed with @sibicramesh earlier today. It also calls Resync during Run() so that it is guaranteed to have run and reconciled every pod once first before returning.

This is required for the 3.13 enforcer which removes stale PUs on startup and would otherwise potentially delete and create them again on a restart.
