Comment 3 for bug 1994029

The current implementation of the undercloud-tolenflush validation tries to read puppet hieradata from ansible_facts. This is completely wrong and never works. We probably should read keystone.conf instead.

Also, token flush job was already removed, before stable/train release, and TripleO supports only fernet token since then. Probably we should remove the validation completely.

Note that we later re-introduced keystone_cron container to purge expired/deleted trusts. We might want to add a validation for that, though that would be less prioritized.
