CentOS: Allow fixing repository url for CentOS Stream

URL of SIG repository is different between CentOS and CentOS Stream.
('-stream' prefixes major version)

This change introduces the `stream` parameter which we already added
to openstack_extras so that users can use the correct repository
without defining the whole url by ceph_mirror.
