Checks Sub Project Leads

Checks Sub Project Leads

Fatih Pointed out to me the existence of ptl's of sub projects,
which show up differently in the INFO.yaml files.

This commit also adds support for gerrit.opnfv.org and git.opnfv.org links.
I don't remember why we were only accepting github links, but that seems strange.
