v2.1.0

This release contains changes in metric paths exported to Graphite, you may need to fix your dashboard when upgrading. Otherwise everything in backwards compatible.

Improvements:

• Refactored export to Graphite, you can now control aggregation interval using graphite_interval option (in seconds), during refactoring some magical path transformation was removed so now we have more predictable path generation. Though Graphite paths changed with this refactoring
• Web interface rewritten using modern Javascript stack - latest React, Webpack instead of Gulp, ES6 syntax
• Aggregated metrics also added to info command reply. This makes it possible to look at metrics in admin panel too when calling info command
• More options can be set over environment variables – see #254
• Healthcheck endpoint – see #252
• New important chapter in docs – integration guide
• Support setting api_key when using Deploy on Heroku button
• Better timeout handling in Redis engine – client timeout is now bigger than default redis_read_timeout so application can more reliably handle errors

Fixes:

• Dockerfile had no correct WORKDIR set so it was only possible to use absolute config file path, now this is fixed in this commit
• Show node version in admin web panel
• Fix possible goroutine leak on client connection close, commit
