CPS-341 Support for multiple data tree instances under 1 anchor
- Updated the parseJsonData method so it can parse JSON with multiple data trees, now it returns a ContainerNode
- ContainerNode holds a collection of NormalizedNodes
- Updated DataNodeBuilder and FragmentRepository as well to support collection of NormalizedNodes
- Added new methods in CpsDataPersistenceService to store multiple Data Nodes
- Added new test cases
- Updated existing test cases and fixed code coverage
- Addressed comments from previous patch
