Updated git submodules

Project: sfc master da790be3d1c58db4336651be0a9a4818af35f955

Remove sfc-rsp-manager

This sub-project was added by https://git.opendaylight.org/gerrit/#/c/38222/
over a year ago but is not used and basically only contains a stubbed
CSS Module. Maybe the intent was to imlplement this Module at some point.
If that's the case then we would want to use blueprint and not CSS. Either
way I just removed the entire sub-project.
