Support Multiple Accounts per GitLab Instance

Problem to solve

As a Freelancer, I want to be able to set the GitLab Personal Token per Git Repository / Project, so I can work with different accounts on GitLab.com

Proposal

In general within Git it's possible to specify Identity Files specifying which ssh key to use. These can referenced per repo in the repos git config so I'm able to use different ssh keys for the same host.

It would be great to have a similar functionality for the Gitlab Workflow Extension, so it's possible to set e.g. a Company and Private Accounts Secret Token for gitlab.com
