Improve continuous tests runner

- Do not run ifup scripts. They restart openssh server and if this
  happens too often, systemd marks it as failed.
- Output newly added out_of_range statistics
- Use bc to compare floating point "$avg" - otherwise, there is a
  warning. Also use herestring syntax (<<<) available in bash and zsh.
