OVS-agent wants to clean flows table by table during restart,
but actually it does not. If one table has same cookie with
other tables, all related flows will be clean at once.
This patch adds the table_id param to the related call
to limit the flow clean on one table at once.

When an external tunnelled network is used as gateway network in an
OVN router, the "Logical_Router_Port" is not bound to any chassis and
the "Logical_Router" is pinned to a gateway chassis, using the list
provided in a "HA_Chassis_Group".
This patch attends to any change in the "HA_Chassis" list of the
"HA_Chassis_Group" to update the "Logical_Router" chassis assigned.
This provides HA functionality in case that the bound chassis
(chassis pinned) fails.

Pin a "Logical_Router" to a chassis when the gateway network (external
network) is tunnelled. When the external network is tunnelled, the
"Logical_Router_Port" acting as gateway port is not bound to any
chassis (the network has no physical provider network defined).
In that case, the router is pinned to a chassis instead. A
"HA_Chassis_Group" is created per router. The highest "HA_Chassis" of
this group is assigned to the router. If the gateway port is deleted,
the pinned chassis is removed from the "options" field. If the
router is deleted, the "HA_Chassis_Group" is deleted too.
NOTE: in the a chassis belonging to the router "HA_Chassis_Group"
changes, the list of "HA_Chassis" will be updated in
``ChassisEvent.handle_ha_chassis_group_changes``. However, a
"HA_Chassis_Group" change is handled by OVN, when assiged.
But in this case we are using this artifact, as commented before,
to "manually assign" (from core OVN point of view) the highest
priority "HA_Chassis" to the router (this upcoming funcionality
will be implemented in core OVN). A new follow-up patch will be
pushed to provide HA functionality and update the "HA_Chassis"
assigned to the "Logical_Router" when the chassis list changes.

If the Nova metadata service is unavailable, the requests.request()
function may raise a ConnectionError. This results in the upper code
returning a 500 HTTP status code to the user along with a traceback.
Let's handle this scenario and instead return a 503 HTTP status code
(service unavailable).
If the Nova service is down and is behind another proxy (such as
Nginx), then instead of a ConnectionError, the request may result in
receiving a 502 or 503 HTTP status code. Let's also consider this
situation and add support for an additional 504 code.

Previously, the code used to clean up old DHCP processes for a network
before creating new ones supporting multiple segments per network
could potentially not be executed first. Since disabling applies to
cleaning the namespace, this could have led to the network setup being
destroyed after being done.
This change moves the part that cleans up the old DHCP setup to ensure
it is executed first.

This change enhances the IptablesFirewallDriver with support for remote
address groups. Previously, this feature was only available in the
OVSFirewallDriver. This commit harmonizes the capabilities across both
firewall drivers, and by inheritance also to OVSHybridIptablesFirewallDriver.
Background -
The Neutron API allows operators to configure remote address groups [1],
however the OVSHybridIptablesFirewallDriver and IptablesFirewallDriver do
not implement these remote group restrictions. When configuring security
group rules with remote address groups, connections get enabled
based on other rule parameters, ignoring the configured remote address
group restrictions.
This behaviour undocumented, and may lead to more-open-than-configured network
access.

When handling the deletion of extra routes we need to handle the case
that the route is already deleted by another call in the time we have
fetched the extra routes and try to delete it. This is a classic race
condition when two calls try to update the routes of a router at the
same time. The default MariaDB/MySQL transaction isolation level does
not suffice to prevent this scenario. Directly deleting the route
without fetching it solves this problem.

Now the "Logical_Router_Port" is updated when a "Logical_Switch_Port"

the "Logical_Switch_Port" belongs to a router; if that check is

When Neutron is killed with SIGTERM (like via systemctl), when using
ML2/OVN neutron workers do not exit and instead are eventually killed
with SIGKILL when the graceful timeout is reached (often around 1
minute).
This is happening due to the signal handlers for SIGTERM. There are
multiple issues.
1) oslo_service, ml2/ovn mech_driver, and ml2/ovo_rpc.py all call
signal.signal(signal.SIGTERM, ...) overwriting each others signal
handlers.
2) SIGTERM is handled in the main thread, and running blocking code
there causes AssertionErrors in eventlet which also prevents the
process from exiting.
3) The ml2/ovn cleanup code doesn't cause the process to end, so it
interrupts the killing of the process.
oslo_service has a singleton SignalHandler class that solves all of
these issues

The "ha" API flag is now enabled for the OVN routers. Because of the
current implementation, this flag must be always "True". When a new
router is created, this flag is always set. If an OVN router is
explicitly created or updated with "--no-ha" (ha=False), the server
will raise an InvalidInput exception.
