[tools] added insert-generated-rows into kudu tools

The insert-generated-rows tool has been merged into the 'kudu'
umbrella toolset.

This addresses KUDU-1628.

Besides, added ability to run multiple inserter threads and
specify additional parameters on batching behavior of the generated
write operations.  It's possible to run data generating sessions
both in MANUAL_FLUSH and AUTO_FLUSH_BACKGROUND modes.  Introduced
sequential and random modes for the data generator.  Overall, these
changes allow to use the tool to measure performance of the Kudu C++
client library in simplistic 'push-as-much-as-you-can' scenario:
the client generates and sends data as fast as it can.
