all meta data has "x-amz-meta" prefix to the name

I was trying to use this gem to set the Cache-Control header for my object like so:

 file_obj.metadata["Cache-Control"] = "max-age=155520000, public"

the result when I fetch the metadata is: "x-amz-meta-cache-control" which is not what I want.

Strangely enough, if I set the Cache-Control metadata via the AWS S3 web console, the Cache-Control metadata does not show up in the files meta data in aws-s3 (it shows all other metadata), but does show up if I inspect the source in Chrome's dev tools.

I don't know if this is intended behavior or a limitation of Amazon's API, but it seems like the metadata commands should have parity with what one can do on the web console.
