> The HEAD operation retrieves metadata from an object without returning the
> object itself. This operation is useful if you are interested only in an
> object's metadata. To use HEAD, you must have READ access to the object.
> Steps:
> 1. Look up the volume
> 2. Read the key and return to the user.
> The AWS reference is here:
> https://docs.aws.amazon.com/AmazonS3/latest/API/RESTObjectHEAD.html
> We have a simple version of this call in HDDS-444 but without Range support.
