Function getConflicts

Resolves schema conflicts between producer and consumer of event following these rules:

• consumer schema can be a subset of the producer schema, ignoring extras
• matched fields (by name) must have:
  • compatible types including format (like guid, date-time, patterns(regex), min, max lengths )
  • required in both, or optional in consumer
  • nullable in both
  • compatible enums - producer is subset of consumer
