KUDU-3429 Add extensive test for delta generation (3/n)
The patch adds a unit test that is a better version of existing tests
to generate UNDO deltas using:
* Pattern of inserting interleaved rows to ensure more rowsets become
eligible for compaction.
* Wide column data to make each mutation size big enough (64KB). Along
with repetitive updates ensures increased delta memory footprint.
* Increased rows per block batch size that ensures compaction op has
more memory footprint, used to hold rowblock and their mutations.
* Use periodic byte pattern to minimize the effect of compression on
wall time and achieve 'compressible on disk but expands in memory'
goal at the same time, for the data generated for UNDO deltas.
* This can act as a de facto unit test for testing high memory
compaction ops. This can be used as a reference base test for any high
memory based compaction tests.
This changelist doesn't contain any functional modifications.
