Support for modern Gluster and Python

[KyleMaas]

This is an immensely useful tool. I've used it in the past (many years ago) and just went to try to use it again, and it does not seem to work with Python 3. Plus, when I tried it on a system with Python 2 where it did successfully run, it did not work with GlusterFS 9 servers. Is it possible this could be updated with work with modern versions?

Okay, so having actually read through the code, I think I've got it partially figured out why it wasn't working with GlusterFS 9. It was trying to put together a chain which didn't make sense and still included a replicate. Found this in the logs:

[2024-10-27 21:08:07.258953 +0000] E [MSGID: 129001] [readdir-ahead.c:1228:init] 0-(volume name)-readdir-ahead-0: FATAL: readdir-ahead not configured with exactly one child 

Once I got that edited so the chain was correct, it worked. So it didn't work out of the box but I was able to get it working, provided you have a Python 2 environment available.
