acme/autocert: support http-01 challenge type

The Manager now loops through known challenge types,
trying to fulfill one at a time until it succeeds or runs out
of supported challenges.

The provisioning of "http-01" challenges can be done
using the new Manager.HTTPHandler method.
It requires listening on unencrypted port 80.

Fixes golang/go#21890
