This reverts commit caae7b6a6f.
Reason for revert:
Many users still need L3 firewalls and Inspur team wants to maintain
this project.
Neutron drivers team discussed the topic of the maintenance of
neutron-fwaas, and agreed to include neutron-fwaas again to Neutron
stadium[1].
Some updates have been made:
Remove use "autonested_transaction" method, see more [2]
Replace "neutron_lib.callbacks.registry.notify" with "registry.publish"
Replace rootwrap execution with privsep context execution.
Ensure db Models and migration scripts are sync, set table
firewall_group_port_associations_v2's two columns nullable=False
