[kolla][masakari] Deprecating Masakari Support in Kolla-Ansible

Hello, Since the Kolla-Ansible CI jobs for Masakari using 2023.2 have been failing [1] due to some time - we are deprecating Masakari support in Kolla/Kolla-Ansible. As I can see - even the OpenStack bot patches have not been merged in 2023.2 branch [2]. If there is anybody willing to go the extra mile of reviving Masakari stable/2023.2 branch - please reach out - ideally by commenting on the deprecation patch in Gerrit [3].
