ray exec and ray attach commands (#2560)

Browse Source 
ray exec CLUSTER CMD [--screen] [--start] [--stop]
ray attach CLUSTER [--start]

Example:
ray exec sgd.yaml 'source activate tensorflow_p27 && cd ~/ray/python/ray/rllib && ./train.py --run=PPO --env=CartPole-v0' --screen --start --stop

This will in one command create a cluster and run the command on it in a screen session. The screen can later be attached to via ray attach. After the command finishes, the cluster workers will be terminated and the head node stopped.
