Can MTR probe be added?

Describe the feature you'd like and the problem it will solve
We would like to run MTR monitoring to discover points of ping failure loss in the network.

MTR probe will not be straightforward, but one interesting way to get MTR on "ping" failure is to use the new alerting feature with command notifier.

This was shared by Nick Zurku in the Cloudprober slack channel:

You could add a stanza like this to your probe config:

  alert {
    name: "high_failure_rate_alert"
    condition {}
    notify {
      ...
      command: "/srv/netprobe/send_mtr_report.sh @target@ @target.label.address@ @probe@"
    }
  }

Basically it will run a shall script on any failure.. that shell script can run mtr and send a report to the given address. I found it really interesting.
