> run.sh is very slow because it's 4 calls to slider, which means 4 JVMs, 4 connections to RM and other crap, for   2-5sec. of overhead per call, depending on the machine/cluster.
> What we need is a mode for llapservicedriver that would not generate run.sh, but would rather run the cluster immediately by calling the corresponding 4 slider APIs. Should probably be the default, too. For compat with scripts we might generate blank run.sh for now.
