Swift get object metadata
To retrieve an object’s metadata, make a HEAD request with the API version,
account, container, and object name. You must have read permissions on the container to retrieve
metadata from an object within the container. This request returns the same header information as
the request for the object itself, but it does not return the object’s data.
