    ARTEMIS-2205 Broker Improvement by caching Routing for most common cases
    
    During AMQP Perf tests this became more relevant on profiling.
    It is a general improvement done as part of this AMQP performance task.

    ARTEMIS-2205 Avoid new Runnable for every message sent
    
    As we now use the netty executor, creating a new Runnable
    for every message received became a relevant CPU, memory and putting extra GC pressure.
    
    By doing this change alone I was able to improve performance by 5% more or less.
