Ihar Hrachyshka be101776c6 Avoid notifying while inside transaction opened in delete_port()
delete_port() calls to disassociate_floatingips() while in transaction.
The latter method sends RPC notification which may result in eventlet
yield. If yield switches a thread to another one that tries to access
the same floating IP object in db as disassociate_floatingips() method
does, we're locked and get db timeout.

We should avoid calling to notifier while under transaction.

To achieve this, I introduce a do_notify argument that controls whether
notification is done by disassociate_floatingips() itself or delegated
to caller. Callers that call to disassociate_floatingips() from under
transactions should handle notifications on their own. For this,
disassociate_floatingips() returns a set of routers that require
notification.

Updated drivers to reflect new behaviour. Added unit test.
