Adding attributes needed for slave configuration.
Might also be good to include some sort of apache config for serving the webgui in the future
commiting recipe for configuring things on the slave
still needs help programmatically _creating_ the slave in the first place
also needs a way to create the jenkins slave user - the way I originally wrote it uses a private cookbook
and finally, it needs an upstart/service to start and run the slave.jar in the background.
running this will start the slave with the proper configs
