Hello Tidy Bot, Kudu Jenkins,

to look at the new patch set (#4).
Change subject: [compaction/test] Add tests to generate heavy rowset compaction
......................................................................
[compaction/test] Add tests to generate heavy rowset compaction
This change implements a better approach to test out
high memory compaction case. There is an existing patch:
https://gerrit.cloudera.org/#/c/19278/
that uses different approach which does not scale
well because of excessive memory usage by client.
Patch contains two tests:
1. TestRowSetCompactionProceedWithNoBudgetingConstraints
(generates deltas with memory requirements under budget)
2. TestRowSetCompactionSkipWithBudgetingConstraints
(generates deltas with memory requirements over budget)
and a helper function:
GenHighMemConsumptionDeltas
Using helper function, callers can generate deltas of different
sizes as per test needs. The size_factor can be used to achieve
that. Increasing size_factor by 1 adds 10MB worth of deltas as
far as rowset compaction memory consumption is concerned.
