Dave Syer 35e8965e0a Add VetoCapableInterceptor so that we can prevent multiple instances
The TraceMessageChannelInterceptor should only be added once to a
channel. Normally this is the case automatically, but when the
application context hierarchy is complex, Spring Integration can
occasionally screw up and add the interceptor twice.

This change uses a Spring Integration specific API (VetoCapableInterceptor)
to prevent the double interceptor from being added.
