def get_flagged_args():
    """get_flagged_args

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.
