FLUME-3025. Expose FileChannel.open on JMX
This patch exposes the FileChannel's open flag on JMX to make it possible to
detect when it wasn't able to start up. In those cases the open flag is false.
This closes #85

> We've encountered an issue several times when the {{FileChannel}} wasn't able
> to start because of some startup-time exception.
> In this case {{FileChannel.open}} stays false {{false}}, exposing this field
> on JMX would make it easier to detect when the file channel hasn't been
> started / or has been stopped because of some reason.
