Ability to mount the same PV across mutiple workspaces (one workspace running at a time)

Is your enhancement related to a problem? Please describe.

We would like to be able to attach a persistent volume (in our case an EFS volume) that is shared across multiple workspaces on Che. This would allow us to share static assets that are stored on an NFS drive with all workspaces of the same project. We work on large web projects where GBs of media needs to be mounted into the workspace.

Describe the solution you’d like

It would be great to be able to define this in the devfile, for example:

  volumes:
     - claimName: pvc-name
       containerPath: "/home/user/media"

Describe alternatives you’ve considered

We thought of using the Kubernetes custom resource section of the devfile but this doesn’t seem to work.

I think that would work really well!

I would also include a accessMode field in this case, in case the requirement is e.g. sharing a ROX volume.
