Review comment:
Can we make the PR title clearer? It seems the SET command can already
set/get hadoop configs in the SQLConf. The only problem is we don't display the
default value correctly, which is from `sparkSession.sharedState.hadoopConf`.
BTW do we have a valid use case? e.g. a hadoop conf is not in `SQLConf` but
in `sparkSession.sharedState.hadoopConf`.
