Warmup servers prior to executing benchmarks about benchmarks

The other thing about these benchmarks are that it doesn't really test GraphQL capabilities. Instead it tries to benchmark the webserver.

We prefer benchmarking on https://github.com/tailcallhq/graphql-benchmarks which are a lot more thorough.

I agree about warming up, PR welcome.

static-rust is a literal webserver benchmark, and the difference between that one and async-graphql/juniper is over 2x. So it's far from "only" benchmarking webservers. But it could certainly be improved (#190), note that this was a side project that I hacked together in a weekend 😉
