cluster / multicore about api

[missinglink]

I experimented with this and couldn't get any better results by using cluster. I think multicore support is enabled by default in express4+ but I couldn't find any docs for this.

here is the branch if anyone else feels like giving it a go: https://github.com/pelias/api/tree/multicore

my results:
