Remove a specific user-defined tag from an asset.

NOTE: If the tag is not on the asset, the request will be treated as successful.

As tagging is an asynchronous operation, the API will wait up to 2 seconds for the backend to complete
but if it is still not complete in that time, the task_ids contained in the response can be used
to continue to check status if the requested operation isn't reflected in later requests.

Even if the response includes complete: true there may still be a slight delay before requests
allow for filtering or presentation of the tag on the asset.
