Some VMs, when already scaled up as much as possible, end up spamming the autoscaler-agent with upscale requests that will never be fulfilled. If postgres is using memory greater than the cgroup's memory.high, it can emit new memory.high events 1000 times per second, which... just means unnecessary load on the rest of the system. This changes the vm-monitor so that we skip sending upscale requests if we already sent one within the last second, to avoid spamming the autoscaler-agent. This matches previous behavior that the vm-informant hand.
