Sensu Grid Versions Save

Merged changes from @naemono for speed optimisation and better logging.

There was a threading leak, requests to the main dashboard view would spin up new threads, but never close them, this is fixed now.

• Fix for #6 when using sensu > 0.26.x version

• adding @joerayme 's events view
• fix threading issues

Getting data for the main grid now uses threads, this should speed things up when having more than one sensu host to query.

Minor changes merged from RiRa12621

The main grid overview displayed all alerts when no match was found, that is fixed now and if there are no alerts, it will show 0 and green :). Also fixed up the Dockerfile to not include all files and fixed a log file permission issue.

There was a bug in building the url in the detail view when filtering. This is now building correctly.

first release

features:

• overview of multiple DCs with OK, WARNING, CRITICAL, DOWN, ACK'd alerts
• grid view per DC
• filter by hosts' subscription (per DC grid and in main Overview)
• filter by multiple subscriptions (manually by adding subscriptions to the URL as comma separated list, see FAQ)
