Issue

installutils.get_server_ip_address fails when setup_dns is set to False

Steps to Reproduce

1. Execute installutils.get_server_ip_address with appropriate parameters setting "setup_dns" to False
2. Receive ScriptError exception;
   Error: the hostname resolves to IP address(es) that are different
   from those provided on the command line. Please fix your DNS
   or /etc/hosts file and restart the installation.
   Provided but not resolved address(es):

Actual behavior

SciptError exception thrown

Expected behavior

List of IP addresses to be returned

installutil code retrieved from GitHub, commit ID 0e0331529921f9e7e436ef9d176d6fd12ec4cc46

Additional info:

The issue is due to the comparison of set(ip_addresses) and set(ips) on line 554, the ips object is a list of ipautil.CheckedIPAddress objects and ip_addresses is a list of strings so of course the comparison will always fail.

Setting setup_dns to True avoids this code path (and also explicitly sets ips = ip_addresses)
