-- | Adds one or more tags to a specified resource. A resource can have up to 10
-- tags. If you try to create more than 10 tags for a resource, you will
-- receive an error and the attempt will fail. If you specify a key that
-- already exists for the resource, the value for that key will be updated
-- with the new value.
