Add SSL (option) to storage command. This is the first step towards adding TLS to mongo<-->agent|client|webservice communication. It adds appropriate options to the mongod command if thermostat is so configured. In order to test this better, I've refactored MongoProcessRunner a bit. Also, DBStartupConfiguration does the parsing of the db.properties file now. As such it's also easier to test. Tests have been added for it too. Finally, I've renamed the c.r.t.agent.cli.db package to c.r.t.agent.cli.impl.db to better reflect in the package name that it is an internal package. Note that you'll need to have a mongod available on your system which understands --ssl* options in order to be able to fire mongod up with SSL enabled. These options are only added if appropriate config is in place in db.properties. Since it defaults to false, it should be OK to be pushed now without breaking existing behaviour. What comes next is adding support on agent/client/webservice side so that they can talk SSL over the mongodb channel as well.
