Add a fetch/ceph_cluster_uuid.conf file so we keep the same UUID from
the Vagrantfile and from the ceph-common run.
Prior to that change the Vagrantfile was setting
4a158d27-f750-41d5-9e7f-26ce4c9d2d45 but while playing the ceph-common
role we check if fetch/ceph_cluster_uuid.conf exists, if not we generate
an UUID. Here we ended up with 2 UUIDs...
IMPORTANT NOTE FOR NON-VAGRANT DEPLOYMENT. IF YOU WANT TO USE YOUR OWN
UUID PLEASE REMOVE THAT FILE BEFORE RUNNING THE PLAYBOOK.

Use Vagrant's built-in support for Ansible provisioner. This eliminates the need
for a hosts file, and simplifies the ansible config file.
Renames config from .ansible.cfg to ansible.cfg since Ansible expects the file
to be called ansible.cfg and be adjacent to Vagrantfile when using the Vagrant
provisioner.
