queue-repair

Hi Roberto,Since Python 2 shall be retired by April 2020 and the original queue-repair cannot run by Python 3.  I created a patch to make it works and tested to run by Python 3.6.8 on CentOS 8 successfully.  Hope the patch is helpful.

It seems to work with both v.2 and v.3 of python. Applied! Thank you.

Thank you. Very much appreciated. I'll check it out
