> {{msck repair table <tablename>}} is often used in environments where the new partitions
are loaded as directories on HDFS or S3 and users want to create the missing partitions in
bulk. However, currently it only supports addition of missing partitions. If there are any
partitions which are present in metastore but not on the FileSystem, it should also delete
them so that it truly repairs the table metadata.
> We should be careful not to break backwards compatibility so we should either introduce
a new config or keyword to add support to delete unnecessary partitions from the metastore.
This way users who want the old behavior can easily turn it off.
