Sometimes it is useful to be able to use the project cleanup function in

New implementation of the project cleanup based on the sdk.project_cleanup.
It is implemented as an additional OSC operation and will ideally obsolete the
`openstack project purge` giving flexibility to extend services support,
parallelization, filters, etc.
