Summary: db_stress to execute DB::GetApproximateSizes() with randomized keys and options. Return value is not validated but error will be reported. Two ways to generate the range keys: (1) two random keys; (2) a small range. Pull Request resolved: https://github.com/facebook/rocksdb/pull/6213 Test Plan: (1) run "make crash_test" for a while; (2) hack the code to ingest some errors to see it is reported.
