Summary: Replace FSWritableFile pointer with FSWritableFilePtr object in WritableFileWriter. This new object wraps FSWritableFile pointer. Objective: If tracing is enabled, FSWritableFile Ptr returns FSWritableFileTracingWrapper pointer that includes all necessary information in IORecord and calls underlying FileSystem and invokes IOTracer to dump that record in a binary file. If tracing is disabled then, underlying FileSystem pointer is returned directly. FSWritableFilePtr wrapper class is added to bypass the FSWritableFileWrapper when tracing is disabled.
