refactor(webapi,types)!: make challenge type extensive

Browse source 
We may allow more challenge types other than PoW in the future, eg.
captcha. So make the relevent types more generic.

Now the challenge is returned in JSON response as a individual top-level
field `register_challenge` instead of in HTTP headers.
