Hang Yang 9f09b1fb19 Support address group in OVS firewall agent
Support security group rules with remote_address_group_id in openvswitch
firewall. This change reuses most of the firewall functions handling remote
security groups to also process remote address groups. The conjunctive flows
for a rule with remote_adress_group_id are similar to others with
remote_group_id but have different conj_ids.

A new API resource ``address group`` and its CRUD operations are introduced
to represent a group of IPv4 and IPv6 address blocks. A new option
``--remote-address-group`` is added to the ``security group rule create``
command to allow network connectivity with a group of address blocks. And
the backend support is added to the ``openvswitch`` firewall. When IP
addresses are updated in the address groups, changes will also be reflected
in the firewall rules of the associated security group rules.
