Adding a wrapper script which removes load-balancer's pidfile and starts the component.
Added instructions to wget zato_start_load_balancer wrapper script.
Changed path to load-balancer to absolute path.
Adding basic Dockerfile which creates an image and Zato load-balancer, but doesn't run the balancer yet - user can run it manually with 'docker run -t -i [image] /opt/zato/zato_start_load_balancer'.
Added ENTRYPOINT instruction - load-balancer is now started automatically when user executes 'docker run -t -i [image].
