features/changelog: Avoid setattr fop logging during rename
Problem: When a file is renamed and the (renamed)file's Hashing falls into a different brick, DHT creates a special file(linkto file) in the brick(Hashed subvolume) and carries out setattr operation on that file. Currently, Changelog records this(setattr) operation in Hashed subvolume. glusterfind in turn records this operation as MODIFY operation. So, there is a NEW entry in Cached subvolume and MODIFY entry in Hashed subvolume for the same file. Solution: Avoid logging setattr operation carried out, by marking the operation as internal fop using xdata. In changelog translator, check whether setattr is set as internal fop and skip accordingly.
