Ability to connect with metabase

[eiso]

I tried adding Gitbase as a MySQL database to metabase but unfortunately it got stuck trying to connect over and over again asking for some variables that weren't supported.

This doesn't have high priority but would be a nice addition to make work.

@ajnavarro do we still want this?

we should leave it here as a feature request.
