> {{testObsRepeatedDefragDoesNotIncreaseCheckpointFootprint}} uses a fixed 16
> KiB tolerance. The footprint counts all checkpoint files, including OPTIONS,
> MANIFEST and LOG, which RocksDB rewrites per column family when re-triggered
> defrag reopens each checkpoint. Adding a single OM table (versionedKeyTable
> in HDDS-15728) pushed the growth to 16402 bytes, 18 bytes over the limit.
> Scale the tolerance with the number of tables in OMDBDefinition instead.
