Create a performance testing plan for Kitura-NIO

[mamabusi]

As discussed and decided upon, this is the priority in terms of performance testing for Kitura-NIO:

Measurements with microbenchmarks with Kitura-NIO vs. Kitura-net Measurements with the same microbenchmarks on Express (All the above can be on Ubuntu 16.04) Measurements of comparing 18.04 to 16.04 Getting TechEmpower running on Kitura-NIO and comparing to Kitura-net

The tasks done in the above task list: Measurements with microbenchmarks with Kitura-NIO vs. Kitura-net Measurements of comparing 18.04 to 16.04 Getting TechEmpower running on Kitura-NIO and comparing to Kitura-net

We must probably identify a list of benchmarks which'd we'd want to run on every pull request, and post comparative numbers on the pull request. We could start with TechEmpower!
