Subject: [PATCH] Add new callbacks event for resouce status update

A new event AFTER_STATUS_UPDATE is added, that will be published to
callbacks when a resource's status is updated in the DB. The first use
of this new event is to indicate when the L3 DB layer has updated
floating IPs status.

Partial-Bug: #2020823
