python-simplestreams contains openstack bits

[Scott Moser]

the python-simplestreams package contains the openstack dependent bits (mirros/glance and such).
there is python-simplestreams-openstack explicitly for this purpose, but as it is, that package is mostly empty other than dependencies.

The fix would be to not collect the openstack files into python-simplestreams, but instead collect them into python-simplestreams-openstack.

Additionally, i'd like to get tools/sstream-mirror-glance into the distro.
