get metadata downloads the entire blob

[yan-hic]

Not sure if it is by design but I have noticed that in order to read the metadata of a blob, the library actually downloads it, before parsing and rendering the metadata dict.
If this is the case, this is highly inefficient e.g. one needs to download a 2GB file to read the content_type or any custom metadata.

If confirmed, this is a showstopper for us.

Also, list_blobs only returns name so can't use it to read the metadata - which would be more efficient.
