server/index.js no longer exports a singleton server via labbable, but rather an async function that returns a server.
So, no more labbable (will be deprecated with a note in its readme)
No more hoek needed as a deployment dep
Added .hc.js for interop with the pal cli (will likely backport this simple change to the existing boilerplate)
Unhandled rejections are treated the same as unhandled exceptions when running the deployment server (in line with node's deprecated treatment of unhandled rejections)
