DWO does not seem to reconcile DevWorkspace after DevWorkspaceTemplate is changed

DWO does not seem to reconcile DevWorkspace after DevWorkspaceTemplate is changed.
P.S. DevWorkspaceTemplate seems to have the right ownerReference set.

Steps to reproduce:

1. Run DevWorkspace with Eclipse Che.
2. Update theia image in DevWorkspaceTemplate of Theia.
   Expected: DevWorkspace deployment is updated with newer image.
   Actual: DevWorkspace deployment uses the old configuration.

Expected: DevWorkspace deployment is updated with newer image.

I'd argue that this is a bad idea -- if there are a hundred DevWorkspaces, any update to the Theia DWT would result in >100 reconciles immediately being queued up, and potentially every DevWorkspace on the cluster restarting.

Agreed that we don't won't to support it. We assign ownerRef for DWT being removed after DW is removed, but we don't want DWT updates - invoke reconcile loop
