Description of problem:

 
foreman-installer --certs-state Texas --certs-regenerate True
 
The installer will see and run as if the state value was changed to Texas, regenerating certificates. However, because kafo.config.app.answers returns the answers file and not the compiled params, what gets written back to the answers file is the original answers at runtime. Thus the answers file now have the previous value (e.g. North Carolina) and the next installer run will trigger a certificate update under the hood.
