Deprecate the nova-manage commands that rely on nova-network

nova-network is deprecated. The 2.36 microversion makes the
network REST APIs fail with a 404. And the network CLIs/APIs
in python-novaclient are being deprecated. So we should also
deprecate the nova-manage commands that use nova-network.
