Improve CPS Exception handling

- Removing unnecessary level of CPS(Validation)Exception
- Moved exception inside spi package
- Rename exceptions are per agreed new exception hierarchy
- Use new exceptions
- Added SchemaSetAlreadDefined Exception
- Added AnchorAlreadyDefined Exception
- Ensure unique serialVersionUIDs
- Fixed CpsAdmin(Persistence)ServiceImplSpec tests (there was a mix-up about what this class was testing)
- Replaced exception builder with dedicated exception (constructors)
