Support json format logs

[kamaradclimber]

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

I'd like to have zwave-js-ui (and all programs launched by it) use json formatted logs. It also easier parsing and analysis (+create some alerts when some patterns emerge).

Describe the solution you'd like

Ideally, this would be configured via settings.json with an option jsonLogs: true. This options would disable color logs and configure the log format to json for the UI and the driver.

Describe alternatives you've considered

I am currently sending my logs to datadog and wrote custom parsers. This is not sustainable and does not handle multiline messages (such as errors) which are usually the most interesting ones. It is also not shareable with other users.

Additional context

Other users have looked for it in the past: zwave-js/zwave-js#5214 #2136 zwave-js/zwave-js#3019. A custom solution has been documented zwave-js/zwave-js#6061.

Solutions presented in threads mentionned above cannot be used at the moment because logConfig from zwave driver is harcoded

will see what I can do and how much interest there is in such feature. My time is limited so I have to give priority to most important things like #4290 that will take lot time

Of course PR are welcome 😄
