Logger is blocking node.js process from exiting when batchInterval is set

See splunk/splunk-bunyan-logger#5

[tbenade]

no movement on this?

@tbenade we would love a PR. Otherwise we will make some progress in the near future

[spencermurray]

How near?

@spencermurray feel free to open a PR for this. I believe something like the following should address the issue, but we haven't had a chance to test this out.

Perhaps this would go in the SplunkLogger constructor:

var that = this;
process.on('exit', function() {
  that.flush();
  that._disableTimer();
});
