Review comment:
Yes metastore client provides an ability to have a filter hook
(configured using metastore.filter.hook), this can be used to filter partitions
on client side. Currently the default implementation doesn't filter anything
though so I decided to leave since it requires api for partitionspec instead of
partition.
