UI: The pool utilization stats should be refreshed
Although the kea->agent->server stats are being refreshed every 10 seconds, the UI is not. Right now user has to hit F5 or cltr-R every time to see updated stats. This is something that should be done automatically.
Eventually, this should be configurable interval, but for the time being having it set to 10s seems reasonable. As for the long term plans, I like what Grafana does. You have a list of intervals you can choose from (1s, 5s, 10s, 30s, 1min, 10min etc). During normal operation you'd probably have it set up to 30s or a minute. However, during emergencies 1s could be useful. (I understand that any value below 10s is not exactly usable right now as the underlying pulling data from the servers updates every 10s, but that too will be configurable one day).
