Option to reduce log output

[kennymc-c]

More of a feature request than an issue:
The mass of log messages at startup of the plugin make it impossible to read the Homebridge internal log messages from startup in the UI. I would prefer to have the option to reduce the messages to a minimum, e.g. to see only error messages.

i think the best way to do this would be to habe a per plugin config option for the log level.

if this is implemented on the homebridge side i would be open to changing the log levels on my side to a different lower level for these startup messages.
