eventutilities: disable row/dict converters
Run atop an eventutilities-python PoC with dict to/from row conversion disabled. This dep is needed to test (on k8s) a mitigation to memory leak that was successful on yarn.
Changes have been tested in YARN (without OOM), but need a new release to be tested in DSE k8s.
The goal of this change is to establish a baseline to track performance regressions.
We might revert once tests have completed.
