scalar: remove mount and unmount verbs

- Remove mount and unmount verbs
- Clone no longer calls mount
- Removed mount-all and unmount-all from the service verb
- Updated functional tests as needed for above changes
- Remove code for unloading the kext from the installer,
  there is no kext for Scalar
- Stop calling 'service --unmount-all' as '--unmount-all' is no
  longer supported.  For now call '--help' instead (until the
  service is able to stop its inflight maintenance task).
