VOL-4805

This script is an inital attempt at capturing and documenting testing
resources for interactive and programatic retrieval.  Command line
arguments and eventual filesystem based detection will hints for a
suite of tests to run to evaluate VOLTHA code changes.

Recreate patch: start over
  o approval given by: daf & torsten
  o a cycle of squashing roaches reported by lint checking resulted
    in multiple conflicting patches in gerrit.  Abandon the mess and
    submit a clean patch.
  o Only delta introduced is using the updated standard copyright notice.
  o git merge to get branch and master back in sync.
