To run the benchmark locally:

 - Install software/slapos-sr-testing and create an instance
 - Source the shell script published by the instance to setup
   environment variables
 - execute `python_for_test -m unittest -v  test.benchmarks`

This promise was generally used to check the connection quality to the
backend with ICMP, by using ping. This is currently obsoleted by health-check
and other parameters in that group.

The parameter to setup the promise is provided by shared instance requester,
that person has no access to those results, as shared instances can't be
monitored directly, all results are only available to the cluster operator in
contrast to health-check, which results are logged to backend_log, to which
shared instance requester has access.
