I think renaming a bunch of configs is not very user friendly. Maybe we should differentiate these configs in our code.

+1. Probably we can add a new param that enlists the params that require a session refresh.

> I guess the {{hive.spark.}} configs were initially intended for the RSC. Therefore when they're changed, we'll re-create the session for them to take effect. There're some configs not related to RSC that also start with {{hive.spark.}}. We'd better rename them so that we don't unnecessarily re-create sessions, which is usually time consuming.
