Review Comment:
@bvaradar We have to list at least one partition path to get the partition
levels for `FileSystemBackedTableMetadata` to ensure the number of partition
columns and partition levels are same. But it might be time consuming
especially for object store.
So here I have to make it more strict for `FileSystemBackedTableMetadata` to
check `urlEncodePartitioningEnabled` also. While we don't need to check it in
`HoodieTableBackedTableMetadata`, since we can simply get one partition path to
check it.
I'm thinking maybe we should enable `urlEncodePartitioningEnabled` if
`hiveStylePartitioningEnabled` is enabled? Since this is the default behavior
for spark and hive
