ContainerCli param added to ceph-base heat template
ContainerCli param added to ceph-base heat template

Added a new param to the heat template that allow operators
to select the containercli used to handle ceph containers.
This parameter is translated in an ansible extra-var passed to
the ceph-ansible playbook, overriding the container_binary fact.
Rebasing to reflect the new project tree.
