METRON-1703 Make Core Profiler Components Serializable

[nickwallen]

All of the core Profiler components are now tagged as Serializable. This allows users to use Java serialization if desired, when running the Profiler in Spark.

Testing

1. Launch the development environment.
2. Ensure alerts are created in the Alerts UI.
3. Ensure the Service Check in Ambari passes.
4. Follow the instructions in the Profiler README to create a simple profile using the Profiler topology in Storm.
