Added scoreboard collection & accompanying dashboards

I enhanced your Apache plugin for a customer to collect and tally the workers scoreboard. Along with this, I created a couple of dashboards to represent that data. 

I'm not sure if you can import the dashboards without being an NR Admin, but if you would like to use them, I can import them for you, if you can share with me the account number from which the plugin is published.

If you have an questions, please give a shout! And great work on this all-encompassing plugin of yours. :)

Thanks,
Seth
