Summary: The patch fixes the build for `db_bench_tool_test` and makes the tests pass. Namely, it fixes the following issues: * https://github.com/facebook/rocksdb/issues/7703 removed the member variable `fs_` but the test case `OptionsFileMultiLevelUniversal` was not updated. * https://github.com/facebook/rocksdb/issues/7344 fixed the `OptionsFile` test case for the case when Snappy is *not* available but at the same time broke it for the case when it *is* available. (The test used a default-constructed `ColumnFamilyOptions` object, and the default value of the `compression` option is either Snappy or no compression depending on whether Snappy is supported.) * The test used `google::ParseCommandLineFlags` instead of `GFLAGS_NAMESPACE::ParseCommandLineFlags`. Pull Request resolved: https://github.com/facebook/rocksdb/pull/7935 Test Plan: Ran the test both with and without Snappy support.

RocksDB: A Persistent Key-Value Store for Flash and RAM Storage
RocksDB is developed and maintained by Facebook Database Engineering Team. It is built on earlier work on LevelDB by Sanjay Ghemawat (sanjay@google.com) and Jeff Dean (jeff@google.com)
This code is a library that forms the core building block for a fast key-value server, especially suited for storing data on flash drives. It has a Log-Structured-Merge-Database (LSM) design with flexible tradeoffs between Write-Amplification-Factor (WAF), Read-Amplification-Factor (RAF) and Space-Amplification-Factor (SAF). It has multi-threaded compactions, making it especially suitable for storing multiple terabytes of data in a single database.
