Merge comsat-servlet and comsat-webactors

[zloster]

For details see #3324.
Also the project directory is renamed to comsat and the benchmark_config.json is adjusted slightly.

The changes are:

• Only one setup-generic.sh build script.
• All dependencies are common now. My quick attempt to make gradle work similarly to the Maven profiles was unsuccessful - I'm able to import dependencies conditionally but the conditional compile was not that easy. I don't know if this will cause problems.

comsat project is OK.
undertow-jersey has failed due to build timeout. There was some problem with the MySQL installation and the installation never finished.
