Summary: Add caching for converted Copycat schemas in JSONConverter
Key: KAFKA-2474

Project: Kafka
Issue Type: Sub-task

>From discussion of KAFKA-2367:
bq. Caching of conversion of schemas. In the JSON implementation we're
including, we're probably being pretty wasteful right now since every record
has to translate both the schema and data to JSON. We should definitely be
doing some caching here. I think an LRU using an IdentityHashMap should be
fine. However, this does assume that connectors are good about reusing schemas
(defining them up front, or if they are dynamic they should have their own
cache of schemas and be able to detect when they can be reused).
