Add devfiles to configure a workspace with GDK
What does this MR do and why?
This MR adds the Devfiles originating from the GDK repository.
This will allow, workspaces to be created from within the monolith repository, for example to facilitate review of a merge request.
For now, the workspace does persist code changes to the monolith, but does not persist database or any other state.
In particular it does - starting from the current "GDK-in-a-Workspace" image - always reconfigure and rebootstrap the underlying GDK, when a workspace is stopped and restarted.
As can be seen in the screen recording / the screenshot below, this takes anywhere from 6 to 10 minutes currently.

How to set up and validate locally
-
Start a workspace from this branch
-
Open the workspace
-
As there is currently no visual indication on the frontend,
tail -f -v /projects/workspace-logs/poststart-std*.logcan be used to track the progress of the post-start script. -
When the script indicates it is finished, visit the GDK's GitLab instance in the browser.
