Minimal reproduce step

SparkCatalog::initialize accepts a CaseInsensitiveStringMap as the input and Options.fromMap(options) will create an Options with lower case keys. https://github.com/apache/paimon/blob/release-1.2.0/paimon-spark/paimon-spark-common/src/main/java/org/apache/paimon/spark/SparkCatalog.java#L125

What doesn't meet your expectations?

Sometimes the catalog options should be case sensitive. For example, the jdbc.socketFactory option will be passed to the PostgreSQL JDBC driver and the driver only recognizes socketFactory, not socketfactory.

We can fix this problem by using the original case sensitive map Options.fromMap(options.asCaseSensitiveMap()).

Anything else?
