Summary:
**Summary**:
Set defaults for high-pri and low-pri thread pools in regression test script.
**Reason for this change**:
With #2680 , high-pri and low-pri thread pools get different numbers than before if `num_high_pri_threads` and `num_low_pri_threads` options are not explicitly passed to db_bench in regression test script ... leading to a false-positive regression.
**Test Plan**:
REMOTE_HOST=udb1671.prn3 TEST_MODE=1 FBSOURCE=~/fbsource ~/fbsource/fbcode/rocks/tools/debug_regression_test.sh viewstate (with very minor changes to the internals).
Observe P50 and P99 which showed up as regressions in our graphs.

Summary:
Tested by running it on a remote machine.
I could not run it on the particular remote machine which has a different location for time command since it is busy and the script does not allow concurrent runs. So I tested it by hacking the script and replacing the command with "\$(hostname)" and confirmed that the scripts prints out the host name of the remote machine.

I tested a variation of the script locally. Any idea how to do run a test that also involves writing to scuba tables?

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

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.

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
