Review comment:
       I understand that we want to have a possibility to configure the 
IcebergInputFormat to be case sensitive or case insensitive since it can be 
used by other MR jobs as well. Do we want to allow the users of Hive to shot 
themselves on the foot and enable case sensitivity?
   My first guess would be that we should not use the configuration here, just 
go with `false`, but if you have some specific use-case in your mind I can be 
easily convinced 😄
