GitLab support for external repositories

Pantheon's external repository integration now supports GitLab in addition to GitHub. You can connect a GitLab repository to a Pantheon site via Terminus using --vcs-provider=gitlab, with support for both GitLab.com and self-hosted GitLab instances.

What's new

• GitLab repository support — Create Pantheon sites connected to GitLab repositories using terminus site:create --vcs-provider=gitlab
• Self-hosted GitLab — Connect sites to self-hosted GitLab instances using the --vcs-host=<your-gitlab-domain> flag
• Token-based authentication — GitLab uses legacy personal access tokens or group access tokens rather than OAuth. Tokens require api and write_repository scopes. Group access tokens also require a Maintainer role or higher to create repositories and manage webhooks.

For full setup instructions, see the external repositories documentation.
