auth: implemented module to authenticate against our GitLab

This helps to have a convenient way to manage and test our personal
GitLab tokens. Those are used for certain API calls like creating new
repositories.

prefill the access token web view as per
https://docs.gitlab.com/ee/user/profile/personal_access_tokens.html#prefill-personal-access-token-name-and-scopes
