KAFKA-4218: Enable access to key in ValueTransformer and ValueMapper
This PR is the partial implementation for KIP-149. As the discussion for
this KIP is still ongoing, I made a PR on the "safe" portions of the KIP (so
that it can be included in the next release) which are 1) `ValueMapperWithKey`,
2) `ValueTransformerWithKeySupplier`, and 3) `ValueTransformerWithKey`.
