CI: disable pipeline jobs for auto-deploy branches on .com
Disable CI jobs for pipelines caused by auto-deploy branches on GitLab.com
The various branches created and managed by the Delivery team and the auto-deploy processes do not need to be deployed into out CI clusters, where they consume resources. They'll not be used by the teams (as far as I could confirm), are based off our master branches, which should be kept green at all times as it is.
Closes #2006 (closed)
