Add snapshot scans to fuzz-itest This adds a new operation to fuzz-itest: snapshot scans at a timestamp. When generating random operations, scans at a timestamp are now in the mix. The generator records how timestamps will progress with writes and is careful to make sure that scans happen in the past. After the test case is generated, but before it is run, the timestamps for the scans are deduplicated and sorted to that we save the state immediately before those (and only those) timestamps. This would fail very often before the REINSERT patches but passes with it. Ran 500 loops of fuzz-itest in dist-test in ASAN with: - KUDU_ALLOW_SLOW_TESTS=1 - --stress_cpu_threads=4 All tests passed.
