Add pooling capability

Add an optional feature that that supports session pooling, wherein
more than one host can be active at a time.
Use beforeInsert() instead of beforeOffer(), where possible.
Move request-id-extraction from policy-managment to feature-pooling.
Combined AdditionalProperties into PoolingProperties.
Finished junit tests for DmaapManager.
Adjusted filters for all XxxState classes, and added testGetFilter to
all XxxStateTest classes.
Always publish Offline message when the internal topic fails.
Remove DelayedExtractor, as it isn't needed.
Renamed ExtractorMap to ClassExtractors, and added property name prefix
to the constructor to give more control over property naming to invokers.
Remove State copy constructor.
Use class name instead of class in ClassExtractors map.
Remove BucketAssignments from ProcessingState.
Remove some TODO items.
Add META-INF for implemented feature APIs.
Fix ClassExtractor bug where it can't find a field in a superclass,
and add a test for classes defined in another file.
Add assembly and rename project directory.
Add more junit coverage.
