Merge grizzly and grizzly-jersey projects

[zloster]

The problem is described in #3324.
Here I move the grizzly-jersey project inside the grizzly folder, modify the benchmark configuration and adjust the setup script. This approach (several separate projects inside sub-folders) is used in Java/play2 project. It's the fastest and the dirtiest.
