  Collects from the execution statement the arguments provided to this script.
  The items are then interpretted and returned.  The object expected are the
  KvP's:
      --os_type - the operating system type to be built
      --os_version - the operating system version to be built
  NOTE: by not using these options, both Debian .deb and Redhat .rpm files are
  generated for the operating systems and versions natively as set by a global
  variable at the top of this script.
  FURTHER NOTE: there should be a
      dist_dir/Docker/<os_type>/<os_version>/DockerFile*
  Present for this script to work.
  CONFIGURATION:  It is part of the standard for this script to run its own
  configuration parameters to generate a:
      dist_dir/scripts/config.JSON
  This is a part of a separate script and is executed by this one in an effort
  to make this code as translatable from project segment to segment.
