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.

make check: run python unit tests

usage:
  % flog.py --help
  % flog.py --usage
  % flog.py --type regression
  % flog.py --attr olt

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.

+flog.py
+-------
+This script will be used as a central resource for identifying tests to run
+when sources are changed.  Invoke with arguments and a list of testing
+resources or jenkins jobs to run will be returned.
+
+Unit tests are included for posterity: make check.
+
+Consider the code alpha quality and highly subject to change.  Initial use
+is inteded for interactive use, over time results will evolve to return
+a list of directories and test suites passed to jenkins for consumption
+or better yet logic able to checkout and invoke (~bbsim) tests locally.
+
+Yes hardcoded jenkins URLs in the meta directory are gross but their
+presence will be short lived.
