Review comment:
@wypoon @rdblue I am trying to apply this patch to the most recently
master branch, and find that the changes to this IcebergSource for Spark3 could
not be applied due to #1783. "SparkTable" is "loadTable" by TableCatalog and in
SparkCatalog, SparkTable is constructed by "new SparkTable(icebergTable,
!cacheEnabled)" with snapshotId and asOfTimestamp set as null internally. It
seems that options given by IcebergSource#getTable() could be not passed here.
Could you please share your thoughts on that? Thanks!
