Under some circumstances we may want to not log to `lightningd`
directly, but rather configure the logging ourselves. This is useful
for example if we want to use `tracing` and `tracing-subscriber` to
add custom handling, or add opentelemetry span tracing.
Changelog-Changed: cln-plugin: Suppress internal logging handler via `with_logging(false)`
Any file in this directory which is executable and whose name only
consists of alphanumeric characters, space, '.', '-' or '_' will be
automatically loaded when lightningd starts (unless suppressed with
commandline options).
