pgbench: add --partitions and --partition-method options.

Browse Source 
These new options allow users to partition the pgbench_accounts table by
specifying the number of partitions and partitioning method.  The values
allowed for partitioning method are range and hash.

This feature allows users to measure the overhead of partitioning if any.
