    geo-rep: Changelog History Crawl failure (#2768)
    
    Issue:
    
    glusterfs-georep-upgrade.py is designed to be run
    before the upgrade.
    
    However, many users missed to run it before the
    upgrade. When they ran it after the upgrade, following issue
    was encountered:
    
    Traceback (most recent call last):
      File "./glusterfs-georep-upgrade.py", line 77, in <module>
        modify_htime_file(args.brick_path)
      File "./glusterfs-georep-upgrade.py", line 61, in modify_htime_file
        shutil.copyfile(pth, os.path.join(path, changelog))
      File "/usr/lib/python3.7/shutil.py", line 104, in copyfile
        raise SameFileError("{!r} and {!r} are the same file".format(src, dst))
    shutil.SameFileError: '/storage/glusterfs/guacamole/.glusterfs/changelogs/
    2020/12/30/CHANGELOG.1609357688' and '/storage/glusterfs/guacamole/.glusterfs/
    changelogs/2020/12/30/CHANGELOG.1609357688' are the same file
    
    This happened because, new changelogs formed after the
    upgrade were already in required directories, thus making
    the source and destination same for shutil.copyfile
    
    Solution:
    
    Added exception handling for shutil.copyfile inorder to pass the
    situation where source and destination are same.
