The interval to do the resync was meant to be configurable but
it was always taking the default values due to the config
being loaded after the decorator gets applied.
This patch is moving away from periodic_task in favor of
loopingcall.FixedIntervalLoopingCall so that we can more easily
enforce the reconcile intervals based on the config
