This change combines the previous puppet and docker files into a single
file that performs the docker service installation and configuration.
With this patch the baremetal version of cinder services has been removed.

Rename the file in the environments directory so that the file name
matches the reference in capabilities-map.yaml.
Old name : cinder-dellemc-xtremio-config.yaml
New name : cinder-dellemc-xtremio-iscsi-config.yaml
The new name includes "iscsi" and that is consistent with the corresponding
Heat template file name (cinder-backend-dellemc-xtremio-iscsi.yaml).
