[8.0] feat(HTCondorCE): add option to submit with SSL

[andresailer]

This let's me submit pilots to DESY, and hopefully also maybe other sites that will do the same.

NEW: HTCondorCE: Added UseSSLSubmission option. Allows one to use a configured DN at given Sites for job submission, instead of proxies or tokens. Only at participating CEs and conditions apply.

PS: Currently pilots are at the site, but DESY still has to configure something to make them run. So maybe there will be more changes.

"UseSSLSubmission" should be added in some documentation.
