When spawning a cluster with EBS volumes, nodes will reattach to old volumes even if they are wrong size #37

To replicate: spawn cluster specifying ebs volume size. Shut the cluster down but do not delete volumes. Create a new cluster with a different volume, and you will see that the the old, incorrectly sized volumes are reattached. Solution: instead of just checking for EBS volume name and cluster ordinal, also check for size. Maybe also add an --create-ebs flag so that we never reattach old, possibly full, volumes.

+1 for checking
