Deployit -> XL Deploy
Correct some phrasing
Include reference to CustomKeystore documentation
change the variable names to something meaningful
Don't need to implement a RestartSSLStep in Java, just use the PythonDeploymentStep.
Make the script a property as well.
do proper housekeeping on the streams
Format the if  / else properly
use a configurable 'restartSslChannelsOrder' property  for the restart step
remove sys.exit, some leftover from debugging the script locally
