Add config option to disable logging to stderr/winevent #2525
Description
Request
Add configuration option to disable sending own logs to stderr.
Use case
Currently Alloy sends all own logs to stderr (or, on windows, to windows events).
These logs cannot be staged, the only option to control stderr output is logging.level.
In windows environment, these logs can flood windows event journal.
If one uses logging.write_to to completely process Alloy's own logs, then duplicating those logs to stderr becomes unnessesary and excessive.
In this case, an extra option to disable output to stderr (while keeping it to write_to) would be handy.
