Aaron Gao 08616b4933 [db_bench] add filldeterministic (Universal+level compaction)
Summary:
in db_bench, we can dynamically create a rocksdb database that guarantees the shape of its LSM.
universal + level compaction
no fifo compaction
no multi db support

Test Plan:
./db_bench -benchmarks=fillseqdeterministic -compaction_style=1 -num_levels=3 --disable_auto_compactions -num=1000000 -value_size=1000
```

Yueh-Hsuan Chiang faa7eb3b99 Improve regression_test.sh
Summary:
This diff makes the following improvement in regression_test.sh:

1. Add NUM_OPS and DELETE_TEST_PATH to regression_test.sh:

  * NUM_OPS:  The number of operations that will be issued
    in EACH thread.
    Default: $NUM_KEYS / $NUM_THREADS

  * DELETE_TEST_PATH: If true, then the test directory
    will be deleted after the script ends.
    Default: 0
2. Add more information in SUMMARY.csv
3. Fix a bug in regression_test.sh where each thread in fillseq will all issue $NUM_KEYS writes.
4. Add --deletes in db_bench, which allows us to control the number of deletes instead of must using FLAGS_num.

Test Plan: run regression test with and without DELETE_TEST_PATH and NUM_OPS

Yueh-Hsuan Chiang fda098461b Allow regression_test.sh to specify OPTIONS_FILE. Add header comments.
Summary:
This patch does the following improvement for regression_test.sh
* Allow regression_test.sh to specify OPTIONS_FILE.
* Add header comments that includes examples on how to run the script
  and introduce all configurable parameters.
* bug fix.

Test Plan: Run the example commands in the header comments of regression_test.sh

Yueh-Hsuan Chiang 8cf0f86d39 Allow regression test to run db_bench at a remost host
Summary:
This patch does the following improvement on the regression_test.sh
* allows db_bench being executed at a remost host while storing the
  benchmark results locally.
* kills all db_bench related processes before running db_bench
* better error handling.

Test Plan:
1. Run regression_test.sh both locally and remotely
2. Run multiple regression_test.sh at the same time and make sure
   i. Only one runs successfully.
   ii. The one that runs successfully will kill all other db_bench
       processes before it runs any benchmark.

Yueh-Hsuan Chiang fca5aa6fcc Initial script for the new regression test
Summary:
This diff includes an initial script running a set of benchmarks for
regression test.  The script does the following things:

  checkout the specified rocksdb commit (or origin/master as default)
  make clean && DEBUG_LEVEL=0 make db_bench
  setup test directories
  run set of benchmarks and store results

Currently, the script will run couple benchmarks, store all the benchmark
output, extract micros per op and percentile information for each benchmark
and store them in a single SUMMARY.csv file.  The SUMMARY.csv will make the
follow-up regression detection easier.

In addition, the current script only takes env arguments to set important
attributes of db_bench.  Will follow-up with a patch that allows db_bench
to construct options from an options file.

Test Plan:
NUM_KEYS=100 ./tools/regression_test.sh

  Sample SUMMARY.csv file:
