Re-work App and Tls Tester models

[binarymist]

• Re-work App model. Remove sequential, publisher and parallel (also from config file). Replace with app.emissary and app.cuc

  • Update mentions of "app.parallel" in https://purpleteam-labs.com/doc/local/workflow/
  • Do Refactor the naming of the variables like port in app.parallel.js in s2ContainersReady #16 . Is now more obvious
  • Can we remove the async keyword on the cucCli.on('exit'? No

• Re-work tls model, extract cuc related stuff into app.cuc

• Test
