Changing glance-manage to use argparse sub-parsers does result in an
incompatible change. This no longer works:

  $> glance-manage db_sync --config-file=...

because --config-file is interpreted as an argument to the db_sync
command rather than a global argument. Instead you now have to do:

  $> glance-manage --config-file=... db_sync

The incompatibility is unfortunate, but the new behaviour is pretty
standard.
