Bug #1696627: Behat HTML report

- Updated details for behat.yml config to BehatConfigManager and a call
to update the file
- Added BehatHooks to get screenshots on fail. Screenshots are saved in the
Behat maharadata directory at /behat/results/html/screenshots
- Added auto-open of report
- Added some explanatory notes on how to run report

If you set the "html" flag as third parameter of the Behat command, you can
generate the HTML report. The report will be saved in the Behat
dataroot under behat/html_results

If you accidentially set the "html" flag as 2nd parameter it will
instead show help info
