This class tests single-hop bulk operations in client caches. Single-hop makes use
of metadata concerning partitioned region bucket locations to find primary buckets
on which to operate. If the metadata is incorrect it forces scheduling of a refresh.
A total count of all refresh requests is kept in the metadata service and is used
by this test to verify whether the cache thought the metadata was correct or not.
