Metadata should use head not get

S3 metadata currently uses the get method, to retrieve the metadata, this is a slightly problematic with bigger objects since all the data needs to be retrieved and transferred.

Regarding to the Amazon S3 documentation [1] the HEAD method should be used to get a objects metadata. This patch addresses this inconsistency.
