rtla/osnoise: Add the automatic trace option
Add the -a/--auto <arg in us> option. This option sets some commonly
used options while debugging the system. It aims to help users produce
reports in the field, reducing the number of arguments passed to the
tool in the first approach to a problem.
It is equivalent to setting osnoise/stop_tracing_us with the argument,
setting tracing_thresh to 1 us, and saving the trace to osnoise_trace.txt
file if the trace is stopped automatically.
