CodePipeline support for GitLab Groups

You can now use repositories in your project in a GitLab.com Group to build, test, and deploy code changes using AWS CodePipeline. Connect your GitLab.com account using AWS CodeStar Connections, and use the connection in your pipeline to automatically start a pipeline execution on changes in your repository. AWS CodePipeline is a fully managed [continuous delivery](https://aws.amazon.com/devops/continuous-delivery/) service that helps you automate your release pipelines for fast and reliable application and infrastructure updates. CodePipeline automates the build, test, and deploy phases of your release process every time there is a code change, based on the release model you define. This launch extends AWS CodePipeline’s GitLab support to include both user and group repos. To learn more about using GitLab.com Group projects with AWS CodePipeline, visit our [documentation](https://docs.aws.amazon.com/codepipeline/latest/userguide/connections-gitlab.html). For more information about AWS CodePipeline, visit our [product page](https://aws.amazon.com/codepipeline/). The new feature is available in all regions where AWS CodePipeline is supported except in the Asia Pacific (Hong Kong), Africa (Cape Town), Middle East (Bahrain), Europe (Zurich), AWS GovCloud (US-West), and AWS GovCloud (US-East) Regions.
