// Removes the specified tags from the specified resources. When you specify a tag
// key, the action removes both that key and its associated value. The operation
// succeeds even if you attempt to remove tags from a resource that were already
// removed. Note the following:
//   - To remove tags from a resource, you need the necessary permissions for the
//     service that the resource belongs to as well as permissions for removing tags.
//     For more information, see the documentation for the service whose resource you
//     want to untag.
//   - You can only tag resources that are located in the specified Amazon Web
//     Services Region for the calling Amazon Web Services account.
//
// Minimum permissions In addition to the tag:UntagResources permission required
// by this operation, you must also have the remove tags permission defined by the
// service that created the resource. For example, to remove the tags from an
// Amazon EC2 instance using the UntagResources operation, you must have both of
// the following permissions:
//   - tag:UntagResource
//   - ec2:DeleteTags
