Put configuration files under configurable folder

Instead of putting baremetal.json and groupvars/all on the
git repo folder for Bifrost, just create a folder (which defaults
to /etc/bifrost) and put those files in there.
This will avoid having a dirty bifrost git repo and having issues
whenever the Bifrost git repo is updated.
Note, you will need to run
'ansible-playbook -e @/etc/bifrost/bifrost_global_vars ...' in order
to load the configuration file variables at execution time.
Check http://docs.ansible.com/ansible/playbooks_variables.html for
more info.
