Initial commit for a Heat template for the Rackspace Control Panel that sets up Grafana

Creates a single node deployment that contains:

Elasticsearch
graphite-api
Grafana
nginx to proxy it all.
You can access the server using the key left behind. Basic auth gets set up for a 'grafana' user, the password being one of the artifacts.
Add default dashboard

Add the default dashboard so that it can be versioned and served from github rather than from a gist

Gayr actually merged the template -- I was too late!
Merge branch 'master' of github.com:rackspace-orchestration-templates/grafana
Add a proper README

This adds a README that looks like all the other Heat template README's in rackspace-orchestration-templates.
Clean up template name and extra dashboard

I had a default dashboard that is now redundant.  I also renamed the template so that it lined up with naming conventions in other heat template repos
