Update : Fix a bug for StatisticCollector.java causes by a change of OpenFlow protocols, with Parameterized JUnit test

* Fixed a bug in the Topology Manager dealing with Archipelagos and clusters. Also fixed a few broken tests.

The bug in question came in two parts:
1) The way a Cluster hashcode was previously calculated meant that any cluster with an ID less than 2^32 was given a hashcode of 0. The Cluster hashCode function has been fixed.
and
2) Archipelagos were previously stored in a HashSet. This was a mistake as archipelagos are by currently mutable objects. This meant that if an archipelago was modified, its hashcode would be modified as well, making it impossible to retrieve the archipelago in question from the HashSet of archipelagos. To fix this problem, archipelagos are now stored in a List.

Add CPAnalyzer module

* Updated pom.xml to reflect Loxigen version update.

* Updating Guava version to keep in step with Loxigen.

Fix bug where it was impossible to remove member or pool if class above (pool for members and vip for pools)  was removed before.

* Fixed IP_TOS match problem.

In MatchUtils.java where the IP_TOS match string is converted into ECN and DSCP fields, incorrect values were passed into each fields constructor. To fix the problem, the ECN and DSCP bits had to be isolated and then passed into each constructor.

* Fixed a bug that had to do with the order of bitwise operations when dealing with IP_TOS matches. By adding parenthesis, we ensure that the 'and' is done before the 'shift'.

* Added null check for Apply Actions Miss property in the table features. This table feature can be inferred if it does not exist.

* Fixed bug that would cause a set_dst_port action to result in a set_src_port action instead. Simple copy paste error.

* Added updated openflowj jar files for the intel experimenter port stats reply.

* Added openflowj javadoc jar.

* Add stats reply serializer for the intel port stats experimenter property.

* Updated pom.xml to reflect Loxigen version update.
