URLSession extensions

URLSession is the recommended way to perform network data transfer tasks. It offers a modern asynchronous API with powerful configuration options and fully transparent backgrounding support. It supports a variety of operations such as:

• Data transfer tasks to retrieve the content of a URL.
• Download tasks to retrieve the content of a URL and save it to a file.
• Upload tasks to upload files and data to a URL.
• Stream tasks to stream data between two parties.
• Websocket tasks to connect to websockets.

Combine extension

• Out of these, only the first one, data transfer tasks, exposes a Combine publisher.
• Combine handles these tasks using a single API with two variants,
  • taking a URLRequest (Example PR: OR-5242 Practice URLSession #68)
  • or just a URL. (in this PR)
