HA: Consider adding HA status command to keactrl [ISC-support #14719]
We've got a feature request from a Kea 1.4.0 beta tester. The user is asking whether we could provide a tool to be used locally for checking the server's HA state. We may consider adding this to keactrl. The implementation could simply send the ha-heartbeat command to the local server via unix domain socket and then parse the JSON response.
