[SPARK-3398] [EC2] Have spark-ec2 intelligently wait for specific cluster
states
Instead of waiting arbitrary amounts of time for the cluster to reach a
specific state, this patch lets `spark-ec2` explicitly wait for a cluster to
reach a desired state.
This is useful in a couple of situations:
* The cluster is launching and you want to wait until SSH is available
before installing stuff.
* The cluster is being terminated and you want to wait until all the
instances are terminated before trying to delete security groups.
This patch removes the need for the `--wait` option and removes some of the
time-based retry logic that was being used.
