Sonar fixes to pooling

Made various changes to the pooling feature to address some of the
sonar issues.
Remove duplicate classes, Pair & Triple.
Fix sonar issue about duplicate process(xxx) methods.
Remove extra items from pom.xml and add assembly builder.
Fix license text in pom.xml, inadvertently reformatted.
Fix a few typos in comments and change LinkedList to Queue.
Move assembly.xml to correct source directory.
Replace ScheduledFuture<?> with CancellableScheduledTask, to satisfy
sonar.
Eliminate "TODO" items: add logging, delay after sending Offline
message.
Add more logging in process(Message) methods.
Begin creating end-to-end junit test, fixed bugs found as a result.
Restore logback-test.xml to WARN.
Fix merge conflict - restored test properties file.
