[neutron][tap-as-a-service][release] Deletion old branches of taas

Hello:

I would like to revive the mail sent by Lajos about this topic: https://lists.openstack.org/pipermail/openstack-discuss/2022-November/031276.... In a nutshell: we don't have releases from Ocata to Stein of TaaS because it was moved out from the stadium projects. However we still have issues with the zuul configs.

Because we can't release an EOL patch, I would ask the release team to remove these 5 branches (Ocata, Pike, Queens, Rocky and Stein) from the git repository. If that is not possible, I'll send patches to these branches to remove the .zuul file.

Regards.
