Management server setup issue

[Robert Ward]

Hello all,

I have run into a problem with the CS MGNT setup. When I run 
cloudstack-setup-management command I get back:
Traceback (most recent call last):
  File "/usr/bin/cloudstack-setup-management", line 24, in <module>
    from cloudutils.serviceConfigServer import cloudManagementConfig
  File "/usr/lib64/python2.7/site-packages/cloudutils/serviceConfigServer.py", 
line 17, in <module>
    from db import Database
  File "/usr/lib64/python2.7/site-packages/cloudutils/db.py", line 20, in 
<module>
    import mysql.connector
  File "/usr/lib64/python2.7/site-packages/mysql/connector/__init__.py", line 
41, in <module>
    import dns.resolver
ImportError: No module named dns.resolver

I have installed the Management server in the past without any issue and this 
just started happening recently.

FYI, my core setup:
Centos 7.7
MySQL 5.7
CS 4.13

I have used both the CS and SB repos and I get the same result.

Any help with solving this is most appreciated.
