> The attached patch introduces netty 4 [1] based tcp broadcasting for the broadcasting feature of the persistent cache.
> It adds an additional configuration option for the broadcasting cache: nettyTcp. The configuration works similar to the tcp configuration. In addition unsafe SSL can be configured with "ssl true".
> The code expects netty to be installed once it is instantiated. Broadcasting cache should also run without netty being available. As long as nettyTcp is not configured.
> Dev testing has shown some improvements in regard of performance.
> Known areas: 
> - Threading: Netty uses lots of threads. This might impact overall performance of OAK and would have to be tested. Threads are currently limited to a hardcoded max number.
> - Configuration: Some areas should be configurable.
> - SSL: can be configured by setting "ssl true" in the nettyTcp configuration. It is currently only for development purposes as it accepts all certificates.
