Be useful to have some diagnostics for zha including:
- average or total rate of packet failures over the last minute/hour/day.
- a quality indicator between 0 and 1 as to how good/reliable the zigbee network is.
- count of updates received from devices
- anything to indicate whether some sort of initiation for a new device was received, number of packets
- anything at all related to adding a device. There is so much stuff in the log not everyone can decipher it. Why is my device not being added? Is it even sending a packet? is it sending the wrong thing? Is it providing nonsense to zha?
