Title: [FLINK-12] Clean up configuration object

- Remove class loader (was inconsistently used and set)
- Objects are stored in their type, rather than as a string
- casting happens on object (for numbers) with fallback to parsing of the string representation
- global configuration reuses config object, rather than re-implementing config logic.
