Summary: As part of the IOTracing project, this PR 1. Caches "FileSystemPtr" object(wrapper class that returns file system pointer based on tracing enabled) instead of "FileSystem" pointer. 2. FileSystemPtr object is created using FileSystem pointer and IOTracer pointer. 3. IOTracer shared_ptr is created in DBImpl and it is passed to different classes through constructor. 4. When tracing is enabled through DB::StartIOTrace, FileSystemPtr returns FileSystemTracingWrapper pointer for tracing purpose and when it is disabled underlying FileSystem pointer is returned.
