    You're right, I've used the Netty prefix just because that values are valid 
only under Netty transport, but a different name is welcome

> By default Netty uses the write buffer high/low water mark to perform flow 
> control while on the event loop.
> Currently these properties are not set in Artemis, that is not being flow 
> controlled properly and is not seeing correct activation of the ReadyListener 
> on NettyConnection when it is considered writable.
> I propose to define TransportConstants.NETTY_WRITE_BUFFER_LOW_WATER_MARK and 
> TransportConstants.NETTY_WRITE_BUFFER_HIGH_WATER_MARK to set the Netty's ones.
