Refactor config options

Doing following:
- Rename top-level config option group called 'cns' to the 'openshift'.
- Rename 'cns.setup.cns_project_name' option to the
  'openshift.storage_project_name'.
- Rename 'scale' option to the 'openshift.scale'.
- Delete ''devices' and 'zone' options from 'gluster_servers' config
  group.
- Delete 'cns.setup.cnd_username' option as unneeded.
- Delete 'cns.setup.cnd_password' option as unneeded.
- Delete 'oc_login' common function as unneeded after deletion of
  'cns.setup.cnd_username' and 'cns.setup.cnd_password' options.
- Remove 'Cns' word from base classes.
- Keep backwards compatibility for old options to make transition be
  smooth.
