can not migrate/ snapshot Hive table whose partition value contains "/"

Apache Iceberg version

1.3.0 (latest release)

Query engine

Spark

Please describe the bug 🐞

java.lang.IllegalArgumentException: Invalid partition data, too many fields (expecting 4): col=2023-03-12/col2=ad_manager/col3=7/7/1/col4=val1/val2/null/null

Current implementation always assume no "/" within the partition value, so it always use "/" to split the partition path into fields.

My recommendation would be adding a option to allow user to specify a splitter.

I think it is the same issue as #7612 and PR #7744 may address it.
