Zhichao Cao e62fe50634 Introduce FaultInjectionTestFS to test fault File system instead of Env (#6414) ... Summary: In the current code base, we can use FaultInjectionTestEnv to simulate the env issue such as file write/read errors, which are used in most of the test. The PR https://github.com/facebook/rocksdb/issues/5761 introduce the File System as a new Env API. This PR implement the FaultInjectionTestFS, which can be used to simulate when File System has issues such as IO error. user can specify any IOStatus error as input, such that FS corresponding actions will return certain error to the caller. A set of ErrorHandlerFSTests are introduced for testing Pull Request resolved: https://github.com/facebook/rocksdb/pull/6414 Test Plan: pass make asan_check, pass error_handler_fs_test.
