   I think one way to solve this issue is to support a `FLUO_JAVA_OPTS` env var.  Any java options set in this env var would be used by the fluo script when starting java processes.  This would allow `FLUO_JAVA_OPTS` to be set on the command line for docker, hopefully enabling a command like the following : 
   
   ```
   docker run -d --network="host" -e FLUO_JAVA_OPTS=-Xmx4G fluo worker -a myapp -o fluo.connection.zookeepers=zkhost/fluo
   ```
   
   Currently `fluo-env.sh` defines a `JAVA_OPTS` env var that is used by the `fluo` script.  Could modify `fluo-env.sh` to pre-pend `FLUO_JAVA_OPTS` to `JAVA_OPTS`.
