XD-530 Add spring-xd-reactor Project

Added reactor-syslog XD module.

Changed to eventLoop dispatcher.

XD-530 Adds support for Reactor via two new abstractions: ReactorSubscribableChannel and SyslogInboundChannelAdapter. The former is backed by a Reactor Processor, which has higher overall throughput with the trade-off that each new instance creates a new Thread of execution for the underlying Disruptor RingBuffer. The latter uses the Reactor TcpServer with the built-in syslog Codec to listen on a port for syslog messages, which it simply passes into the output channel without modification. Included in this commit is a basic XML schema for a Reactor namespace and a couple of integration tests.

XD-530 Rename channel implementation to ReactorPublishSubscribeChannel and update the schema to reflect the behavior of this implementation. Also added the submodule to the project.
