Add credentials cache for novajoin user
Add credentials cache for novajoin user

With a switch to using the ansible-freeipa modules instead of the
community modules, we need to specify a credentials cache file.
We need to change to ansible-freeipa modules because the community
modules do not support FIPS.
This is required for the tripleo-ipa change[1].
