:raises: neutron.plugins.ml2.common.MechanismDriverError
if any mechanism driver create_network_postcommit call fails.
Called after the database transaction. If a mechanism driver
raises an exception, then a MechanismDriverError is propagated
to the caller, where the network will be deleted, triggering
any required cleanup. There is no guarantee that all mechanism
drivers are called in this case.'
