OVN backports for Neutron Ussuri

[Corey Bryant]

[Impact]
The upstream Neutron stable/ussuri branch is in extended-maintenance mode which means patches are still accepted but they aren't cutting any new stable releases. Therefore this bug is being opened to backport a series of OVN patches that are needed for functionality on Ussuri (Focal).

Specifically the following bugs require fixes:
LP: #1914394
LP: #1946588
LP: #1951872
LP: #1961013
LP: #1965819
LP: #1927077
LP: #1953295
LP: #1928031
LP: #1952550

[Test Case]
The following SRU process was followed:
https://wiki.ubuntu.com/OpenStack/StableReleaseUpdates

In order to avoid regression of existing consumers, the OpenStack team will run their continuous integration test against the packages that are in -proposed. A successful run of all available tests will be required before the proposed packages can be let into -updates.

The OpenStack team will be in charge of attaching the output summary of the executed tests. The OpenStack team members will not mark ‘verification-done’ until this has happened.

[Regression Potential]
In order to mitigate the regression potential, the results of the
aforementioned tests are attached to this bug.

[Discussion]
All of these patches have already landed in the upstream stable/ussuri branch.
All of these patches have also been included in later stable releases of neutron in Ubuntu. The last of these patches are included via the following point releases:

https://bugs.launchpad.net/cloud-archive/+bug/1975634
