Subject: [PATCH] integration tests: use dstat to monitor system

Dstat is a tool used to monitor system in real-time. It's used by
Devstack in OpenStack gate to monitor system during jobs.
This tool would be useful for Puppet OpenStack Integration jobs so we
would be able to monitor the system during Puppet & Tempest runs, and
help us to debug eventual failures.
