Description of problem:
katello-agent failed to connect because qdrouterd it is not listening to an IPv6 address (it's listening just to an IPv4 address)

Version-Release number of selected component (if applicable):
Saltelit 6.2

katello-ca-consumer-scgxp0287cld.prod.cloud.ihf-1.0-1.noarch
katello-host-tools-3.0.2-1.el7sat.noarch
katello-host-tools-fact-plugin-3.0.2-1.el7sat.noarch
katello-agent-3.0.2-1.el7sat.noarch

How reproducible:
netstat -tlpn | grep qdrouterd
tcp        0      0 0.0.0.0:5646            0.0.0.0:*               LISTEN      19584/qdrouterd

changing the "listener" in /etc/qpid-dispatch/qdrouterd.conf doesn't work, we'll get the same results.

from

listener {
    addr: 0.0.0.0
    port: 5647
    sasl-mechanisms: ANONYMOUS
    ssl-profile: server
}

to

listener {
    addr: ::
    port: 5647
    sasl-mechanisms: ANONYMOUS
    ssl-profile: server
}

=> Same results, won't work
