This patch is adding support for the router_availability_zone extension
for Neutron.
The OVN driver will now read from the router's availability_zone_hints
field and schedule the router ports onto OVN chassis belonging to those
AZs.
Since the OVN driver does not rely on the L3 agent, this patch does not
re-use the configuration option for the agent to configure the
availability zone that a Chassis belongs to (even because there's no
configuration file in nodes such as networker nodes). Instead, this
patch reuses the "ovn-cms-options" field from the local OVSDB to
configure the Chassis. The follow syntax has been used:
$ ovs-vsctl set Open_VSwitch .
external-ids:ovn-cms-options="enable-chassis-as-gw,availability-zones=az0:az1"
In the example above, the Chassis has been configured to belong to two
AZs: "az0" and "az1".
This patch also implements listing the availability zones:
$ openstack availability zone list
As well as validating the router's availability zone hints:
$ openstack router create --availability-zone-hint az0
--availability-zone-hint az1 test_router
The above command would fail if there's no "az0" and "az1" configured in
any OVN chassis.
Documentation for this feature is being written and will be submitted
in a separated patch.
