Discovery fix on restart HASS + adding the timestamp of last received zigbee message visible in HASS

[ugrug]

• On restarting Home Assistant, resending device discovery information
• Add timestamp on receiving message from Zigbee
• Add last_message into MQTT info for devices

why do you rediscover on hass startup? these messages are retained by the mqtt broker.

[ugrug]

On restarting hass without restarting zigbee2mqtt causes my zigbee devices disappear. If this only issue on my configuration, possible caused by using rabbitmq.

[Koenkk]

Can you view the retained MQTT messages?

[ugrug]

I think this issue only on using another broker instead of hass internal mqtt broker.

[Koenkk]

I use an external mosquitto which works without problems.

[ugrug]

I'll check retained working on rabbitmq.

MQTT discovery rely on persistence not enabled in my configuration. I'll move adding timestamp to separate request.
