Fixes Tacker auth and fernet keys dir

Fixes Tacker auth and fernet keys dir

Tacker authtoken was missing password which is now added in the tht
patch.  Tacker also needs 'etc/tacker/vim/fernet_keys' in order to be
able to create VIMs.  The real fix to this missing directory is to the
rpm itself:

However in this patch we ensure it is created in Ansible because
RDO images are frozen in for now in Apex so we would not pick up new
RDO packages.
