Allow url modification for Gitlab

As an engineer I would like the ability to modify the full URL including the last subdomain.

For example for the elasticsearch-kibana instance I would like the ability to modify kibana in kibana.some.host.com

changed title from Update URLs to allow subdomain modification to Allow url modification for Gitlab

changed the description

Already allowed via:

https://repo1.dso.mil/platform-one/big-bang/apps/developer-tools/gitlab/-/blob/main/chart/values.yaml#L52
