[STORM-1066] add current directory for worker process launcher
Currently, when supervisor launches a worker, the current directory of the worker process is not specified. In that case, the worker will be launched with a current directory as ".", which is a random directory. It can cause problems especially when the worker needs to dump something to its current directory.
To fix this, we should enable ProcessBuilder to specify worker's current directory as worker-root/worker-uuid.
