Note on cqueues/lua-http

With this release we're adding a new server backend for Lapis. Although the
backend is functional, there are some things that aren't available yet.
Database connections are shared across all requests so you have to be careful
about leaving transactions or state open. Additionally, there's no way to spawn
multiple workers. For production environments we still recommend OpenResty.
