Public bug reported:

In some cases all DHCP agents become unavailable for neutron-server
(primary cause of that is an issue with amqp), so network rescheduling
will remove networks from all agents. When then agents will be available
again, autoscheduling will not happen because there is no reason for
DHCP agents to do full sync or request available networks.

This can be solved from agent side, but preferable way is to not remove
network from agents if there are no alive agents available.
