KUDU-1861: add range-partitions to loadgen tables
This patch adds the ability to generate a range-partitioned table with
the loadgen tool. The range partitioning schema is designed such that
the non-random write workload will insert sequentially on the primary
key, provided the number of threads is equal to the number of tablets.
This sequential workload per tablet both reduces the number of
compactions and avoids bloom filter lookups.
This patch also renames --table_num_buckets to
--table_num_hash_partitions, which can be combined with
--table_num_range_partitions if desired.
I tested this out on a singler-tserver cluster and verified via the
metrics logs that the number of bloom lookups for a non-random workload
where the number of insert threads and the number of tablets were equal
stayed at zero. When the number of threads was not a factor of the
number of buckets, the number of bloom lookups was non-zero. See
TestNonRandomWorkloadLoadgen in kudu-tool-test.cc for more details.
