ARTEMIS-262 Fix Bridge OOM exception
Netty 4.x uses pooled buffers. These buffers can run out of memory when
transferring large amounts of data over connection. This was causing an
OutOfMemory exception to be thrown on the CoreBridge when tranferring
large messages. Netty provides a callback handler to notify listeners
when a Connection is writable. This patch adds the ability to register
connection writable listeners to the Netty connection and registers the
relevant callback from the Bridge to avoid writing when the buffers are
full.
