[OVN] In stable branches we don't run neutron-tempest-plugin tests

[Maciej Jozefczyk]

We don't run neutron-tempest-plugin tests in stable branches, at least with networking-ovn...

Example:
https://41620a559c5090d887c6-f99336677cbcb935a72dddbf18215860.ssl.cf5.rackcdn.com/731477/2/check/networking-ovn-tempest-dsvm-ovs-release/5f1b8f3/testr_results.html

600~ tests were triggered instead 1200~...

Because of the line [1] the "INSTALL_TEMPEST" variable is False on stable branches, to not mix stable code requirements with master tempest plugin.

neutron-tempest-plugin is not installed while testing networking-ovn on stable branches.

Recently this change was merged [2], that enables installation of tempest in separate py3 only venv. So that we can run new tempest in stable branches.

Maybe we could somehow install neutron-tempest-plugin in that venv instead globally? That could enable running the tests on gates.

I need to check that stuff again, but from what I remember INSTALL_TEMPEST to False is needed to avoid it on system (not venv), and actual fix is to switch away from deprecated all-plugin to all tempest target

(it looks like from quick grep in zuul.d/networking-ovn-jobs.yaml that all-plugin env is used)

Maybe networking-ovn needs something similar to https://review.opendev.org/#/c/730379 (fix for networking-bgpvpn)

[Ghanshyam Mann (ghanshyammann)]

It need little more than just using 'all' tox env. we discussed on IRC and found job needs to enable the neutron-tempest-plguin with tempest_plugins var so that devstack can install it in Tempest venv.

Maciej trying that - https://review.opendev.org/#/c/731477/3

Looking at similar tempest jobs in master and stable branches seem to show number of tempest jobs are equal, so will close this. Plus networking-ovn is no more...
