Upgrade Scrutineer to use ES 0.19.10 client library.  No, this isn't the latest, yes I realise that..
Ensure that Scrutineer reports an identifiable 'node.name' when joining the ES cluster so that it's easier to identify in the ES cluster logs.

Pull out a NodeFactory class that constructs the Node object based on the expected properties needing to be set.

Pull out the Command Line object to a top-level class.
Change the log4j configuration to use some more standard logging patterns which at least emit some local time element.

It's not easy to take the time-since-jvm-start in any meaningful way, at least for us.  Ensure we also leave behind a log file for posterity.
Add the logs directory to be ignored.
