Added benchmarks project and basic benchmark

[davidfowl]

• Added a benchmark project (using benchmark.NET)
• Copied most of the infrastructure from kestrel and tweaked it a little
• Added a resolve benchmark

Does RPS bring any value here?

[davidfowl]

@khellang That's a good question. I like those big numbers 😄

Does RPS bring any value here?

Its easier to evaluate than 0.0001 ns

[benaadams]

Quite fast... might need to stick it in a loop to be accurate :)

I don't like copying same code around, would prefer having package with benchmark.net specific code

I knew you were going to say that. Will postpone this until then.

Also which thing do you want to be common between the repos? The config here is different. I can get rid of the RPS column, that's a shared component we can have. With the inner loops, the time is usable.

[pakrym]

Program.cs code can be shared too

[davidfowl]

Like 5% of the code, the enum (which is a hack) isn't sharable. It really needs to be based on type names, not an enum.

[pakrym]

We need to make it type based not enum based anyway, so it would be 100%

[davidfowl]

It needs to be rewritten is my point. Anyways, I'll add a package to Common with those 2 shared functions.

Also filed dotnet/BenchmarkDotNet#386

here is nice comparison:

[davidfowl]

@AresPr yes, see #490

[pakrym]

@davidfowl do we want to contribute RPS column to BDN?

[davidfowl]

@pakrym Yes, I was just asking @benaadams if he wrote it. It really belongs there.

[benaadams]

RPS came from @mattwarren
