Bill Cromie fce29be335 Add a route to handle Mandrill's webhook URL check
Mandrill's Inbound API checks to see if a URL exists before it creates
the webhook. It sends a HEAD request, to which we now return a 200 OK
response to indicate that the route exists.

Now we can generate inbound API calls with ease on Mandrill, without
having to shuffle around tokens in production.

Fixes #37609.
