Tim Burke 17aa6c789e Port from optparse to argparse
Why now?

* argparse was introduced in Python 3.2 and back-ported to Python 2.7.
  Until we dropped Python 2.6 support, we were stuck on optparse.

* keystoneauth.loading.cli provides register_argparse_arguments and
  load_from_argparse_arguments helper methods. Now that we're moving
  toward Keystone Session support, argparse seems required.
