Make workspace images auto run when workspace base image updated

MR: Pending

Description

Currently, when we publish a newer version of workspace base image, then we would need to make a new MR for updating any workspace images depends on the base image manually.

The reason is, we need to publish the workspace base updated image first, by merging its MR into master. Then create a new MR for updating any other workspace images using the base image.

The step is manual, and would require some efforts. In this issue, we would like to make the process automated.
