Ability to delete Instance Start Data

Currently NAC allows purging of workflow instance as a whole at workflow level. We want a way to purge (delete) Instance Start Data but still keep the Instance activities data. This allows a way to delete any business data to be stored in NAC for compliance reasons but retain workflow execution history and run action history which will be useful for developers for troubleshooting.

This will also satisfy data residency requirements enforced in many industries including financial for compliance enforcement.

Also, we want this feature to be enforced at tenant level that way administrators can force the deletion of initiation start data as soon the workflow completes.
