GitLab project based rooms

Problem to solve

As a GitLab user, Gitter doesn't allow me to create rooms linked to a GitLab project. If my account is linked to GitHub I can create a room that is linked to a GitHub project. Have the room linked to the correct project is important so that short links work (eg. #44 links to issue 44).

Proposal

When signed in as a user linked to GitLab:

• when Creating a room, suggest creating a room based on my GitLab projects
• show a list of GitLab projects to choose from

A follow up issue will be required to add support for personal projects which do not have a group (considered a namespace in the GitLab API) -> https://gitlab.com/gitlab-org/gitter/webapp/issues/2397
