Adds a method for setting a custom media type key prefix used by the fetch handler. This allows both overwriting a built-in prefix (for reasons?) as well as supplying a custom media type. I added this because I was getting an error on `FetchHandler` when pulling docker plugin images which have their own media type. Signed-off-by: Brian Goff <cpuguy83@gmail.com>
