Implement actions on end next to actions on threshold. A new option,
--on-end is added, parallel to --on-threshold. Instead of being
executed whenever a latency threshold is reached, it is executed at the
end of the measurement.
For example:
$ rtla timerlat hist -d 5s --on-end trace
will save the trace output at the end.
All actions supported by --on-threshold are also supported by --on-end,
except for continue, which does nothing with --on-end.
