Bug#835210: grafana: new upstream version 3.1.1 available

[Michael Prokop]

Package: grafana
Version: 2.6.0+dfsg-3
Severity: wishlist

Grafana v3.1.1 is available since beginning of August 2016,
would be nice to see v3.x in Debian to have that available for
stretch then. :)

Thanks for maintaining grafana!
