This adds scripts using Selenium Webdriver to verify
the dashboards for Gafana, Nagios, and Prometheus are
reachable and functioning as expected. The scripts
create screenshots of each dashboard as well as
pages that can be navigated to.
It also adds the scripts to the gates for the single
and multinode deployments.
