Added support for instrumenting short-lived processes:
- The new Application.Shutdown method allows applications to report data to New Relic without waiting a full minute.
- The new Application.WaitForConnection method allows your process to defer instrumentation until the application is connected and ready to gather data.
- Full documentation here: application.go
- Example short-lived process: examples/short-lived-process/main.go
Error metrics are no longer created when ErrorCollector.Enabled = false.
Added support for http://wwwgithub.com/mgutz/logxi. See https://github.com/newrelic/go-agent/blob/master/_integrations/nrlogxi/v1/nrlogxi.go.
