OTA Update progress

[wolph]

Is your feature request related to a problem? Please describe.

The recently added OTA support works great, but the Z2M support has improved in the mean time meaning it can be improved a lot more :)

By parsing the logs, which are available through MQTT now, we can show a progress bar for the OTA update.

Describe the solution you'd like

Show a progress bar based on zigbee2mqtt/bridge/log. Example messages:

{"type":"ota_update","message":"Update of '0xccccccfffe90bcfd' at 45.75%, +- 56 minutes remaining","meta":{"status":"update_progress","device":"0xccccccfffe90bcfd","progress":45.75}}
{"type":"ota_update","message":"Update of '0xccccccfffe90bcfd' at 46.28%, +- 55 minutes remaining","meta":{"status":"update_progress","device":"0xccccccfffe90bcfd","progress":46.28}}
{"type":"ota_update","message":"Update of '0xccccccfffe90bcfd' at 46.8%, +- 55 minutes remaining","meta":{"status":"update_progress","device":"0xccccccfffe90bcfd","progress":46.8}}
{"type":"ota_update","message":"Update of '0xccccccfffe90bcfd' at 47.33%, +- 54 minutes remaining","meta":{"status":"update_progress","device":"0xccccccfffe90bcfd","progress":47.33}}
{"type":"ota_update","message":"Update of '0xccccccfffe90bcfd' at 47.85%, +- 53 minutes remaining","meta":{"status":"update_progress","device":"0xccccccfffe90bcfd","progress":47.85}}
{"type":"ota_update","message":"Update of '0xccccccfffe90bcfd' at 48.38%, +- 53 minutes remaining","meta":{"status":"update_progress","device":"0xccccccfffe90bcfd","progress":48.38}}

A text message is available as a verbose solution. And the progress key is the percentage.

Additional context

Additionally this feature could be used for generic log viewing in Zigbee2MqttAssistant which would be very useful.

We have a plan to capture the log file from Z2M, at least in real time, not from Z2M actual logs.. however..

Just so you all know, the last week there has been like 7 new bugs/issues/requests. I/we (@carldebilly) are not ignoring them, it is just a fact that the SARS-Covid-19 virus is causing some problems focusing on this project. Day-job is in quarantine, meaning normal work hours vary, and available extra hours are limited. I/we will get back on this when things settle down.

Would that work if it's running on a different machine?

No worries, many of us have the same issues :) My productivity is roughly halved right now
