Add Git/GitLab/Github to onprem.vcs section #58

For #58 and added vcs

Git is a command line software rather than a standalone software or a service. So I think it does not fit to this project. How do you think about it? (we should support only GitHub and GitLab)

[gabriel-tessier]

There's git server:

We use it with https://github.com/sitaramc/gitolite, I thought also as generic git server that it can include any less known service, or not added yet.

Oh I didn't know about that. Thank you for letting me know the Git server.
