Add annotation/attribute to disable scale-to-zero on DevWorkspace failure

[amisevsk]

Description

When a DevWorkspace enters a failed state, the deployment for it is scaled to zero. This means that any logs that could be used to debug a CrashLoopBackoff are unavailable.

It would be great to have an annotation or attribute we can apply to DevWorkspaces to disable the scale-to-zero behavior and allow users to view logs when required.
