Refactoring db_stress.cc (#3902)

Summary:
We use `db_stress.cc` intensively to test and verify the behavior of RocksDB. Sometimes we need to add new tests for recently added features. Original `StressTest` class provides many general functionality that can be leveraged by other tests. Therefore, in this refactoring PR, I try to identify the general operations as well as operations that future tests most likely want to customize. Future tests can inherit `StressTest` and overriding the virtual functions to test custom logic.
