Public bug reported:

Some external plugins might need to prevent the attachment of a subnet
to a router, like reported in bug [1]

Now that [2] has been fixed, we can prevent this attachment by adding a new BEFORE_UPDATE callback in ML2, which will be triggered when the router port gets updated by the l3plugin.
Raising an exception during the processing of the BEFORE_UPDATE call should result in preventing the attachment of the subnet to the router.
