Multiple files deletion
In order to delete multiple files you need to send the DELETE request to the search endpoint that specifies a query.
All files matching that query will be deleted. The actual delete operation is implemented as the background operation which identifier
is returned in the response. Later you use it to ask about the delete operation status.
