This adds a method for getting a count of instances in a specified vm_state. We want to use this to limit the number of pending resizes per user for checking quota. When a user reverts a resize to a smaller flavor, there is a possibility of exceeding cores and ram quota because quota is not checked during a revert, so as not to block reverts.
