Title: Make elasticsearch.in.sh more configurable via env

It's easier to manage a configuration through environment variables than
through a config file if that config file has static values that need to
change each version (such as the ES_CLASSPATH). Trying to keep that in
Chef is tedious whereas just controlling these few settings with
environment variables like most of the other settings in here is simple
and straightforward.
