Start building support for running multiple HTTP servers.

The standard use case for this is going to be running a TLS and a non-TLS
HTTP server. I can't see a need for *more* than two, but it is theoretically
possible.

We shouldn't have to change anything with the database or anything; it
should suffice to simply spin up more HTTP servers, and they should
interact with each other the same way a single HTTP server with multiple
threads will.
