resulting in additional fields being output when round-tripping data from previous releases, and failing round-trip tests.

To resolve this, a `<group>.<version>.<kind>_after_roundtrip.[json|yaml|pb]` file containing the 
expected data after roundtripping can be placed beside the serialized data file from a previous release.

These `after_roundtrip` files are generated by running the failing round-trip tests with `UPDATE_COMPATIBILITY_FIXTURE_DATA=true` set.
