Create a Bulk Action to permanently delete docs

Today there is a bulk action to Trash documents, but if you want mass delete you have to go through a Bulk Automation Action using the Document.Delete operation, this approach is not efficient because of the cost of the automation stack.

A new bulk action should be provided, probably limited to Administrator, the action could perhaps share the bulk/trash topic to avoid topics proliferation.

The NXQL provided could be limited to avoid creating orphan documents on completion. For instance it could be limited to a doc id (or a list) in order to remove all descendants.

This action could be limited to MongoDB back-end because it supports delete producing orphan docs (which is not the case on VCS) so delete don't have to be ordered.

Indeed there is already a DeletionAction that is removing doc at low level without checking for descendant so it might create orphan docs (placeless doc)
and this bulk action is not http exposed.
