[apache#1455] improvement(all) Refactor catalog property mapping to e…
…ngine property (apache#1458) ### What changes were proposed in this pull request? Use the new `PropertyConverter` in `catalog-common` to replace the old one. ### Why are the changes needed? We must provide a uniform property mapping system between Gravitino and the query engine. Fix: apache#1455 ### Does this PR introduce _any_ user-facing change? N/A. ### How was this patch tested? Existing test can cover this change.
