Support downloading packages in parallel, with multiple connections per package (similar to apt-fast)

Description of the new feature/enhancement

Support downloading packages in parallel, with multiple connections per package. Concept is similar to apt-fast. Especially useful for folks with intermittent/slow internet connections.

[MarkusTeufelberger]

Bonus points for downloading the same package in parallel from different mirrors, or at least one package per mirror.

[madcampos]

It would be nice if the download process uses something like torrent or other peer to peer method.

I support it!

[zakius]

I'd say it's useful for people with fast connections as they can saturate one source easily and/or get severely slowed down by handshakes

#151 Support Delivery Optimization includes the technology for parallel downloads. We will have some service side work necessary to enable this, and not all servers support range requests (so it will not work for all packages).
