cloudfns: send email updates when the wiki changes
This change introduces two cloud functions: wikiwebhook and
sendwikidiff. The former handles GitHub Wiki change events
sent over HTTP and enqueues them on a pubsub topic for the
latter to pick up. sendwikidiff then checks out the wiki
repo and sends an email with the diff of the change to
golang-wikichanges@.
The reason it is split into two functions is due to GitHub’s
timeout limit on webhook handlers (ten seconds). In testing,
a cold boot of a function that does everything described
above would sometimes hit that limit.
Updates golang/go#27313
