Remove a webhook subscription for 'all' events from the specified location.
If the optional locationId parameter is supplied, the referenced webhook will be the one registered against the supplied location. If no location is specified (or the reserved ID of all is submitted) then the webhook that is removed will be the global webhook, meaning any event from any subscribed location. The omission of both locationId and event effectively results in the call becoming ~/webhooks/all/all.
