#7916298: merge tools/db_crashtest2.py into tools/db_crashtest.py

Browse Source 
Summary:
merge tools/db_crashtest2.py into tools/db_crashtest.py

python tools/db_crashtest.py -h  # show help message, ALL parameters can be overwrite by arguments

Example usages:
python tools/db_crashtest.py blackbox  # run blackbox with default parameters
python tools/db_crashtest.py blackbox --simple
python tools/db_crashtest.py whitebox  # run whitebox with default parameters
python tools/db_crashtest.py whitebox --simple

all default parameters are identical to previous version.

Test Plan: `make crash_test` and make sure it can run with expected parameters pased to db_stress.
