Refactor region handling and persistence

Browse Source 
- Make kryo in AbstractKryoStateMachineSerialisationService aware of same classloader
  most likely use in an app. This takes away some of those weird kryo
  errors you see with a web apps.
- Add context references concept to StateMachineContext which can be used
  to store reference id and then individual running machines with regions
  can independently store their states. Whole machine state can then get
  restored more accurately.
- Add new `region(String id)` to StateConfigurer which can be used to set region id.
  This is equivalent as setting region id with json based machine structure where
  you need to define region id's with orthogonal regions are in use.
- Add new datajpamultipersist sample showing running regions and how those are
  persisted to a database.
- Fixes #617
- Fixes #605
- Fixes #615
