healthcheck in clustercheck container doesn't work with ipv6

[Damien Ciabrini]

The healthcheck script for the clustercheck service uses curl to poll an galera-monitor service started by xinetd. The address of that HTTP service is parsed from a xinetd config.

Currently, the galera-monitor service is configured to bind to a IP address, and not a fqdn.
When the HA overcloud is deployed with IPv6, curl ends up trying to access an URI whose IPv6 is unquoted, and ends up in failure:

[root@controller-0 ~]# podman exec -u root -it clustercheck bash
()[root@controller-0 /]# grep bind /etc/xinetd.d/galera-monitor
        bind = fd00:fd00:fd00:2000::c9:9200
()[root@controller-0 /]# /openstack/healthcheck

000 :0 0.000000 seconds
curl: (3) IPv6 numerical address used in URL without brackets
()[root@controller-0 /]# echo $?
1

    clustercheck: use fqdn instead of ip for bind address

    Clustercheck service is accessible via port 9200 on the Mysql network
    (e.g. internal API). The bind address specified in the config currently
    uses IP address. This breaks the OpenStack healthcheck because curl
    refuses to fetch a URI with unquoted IPv6 address.

    Use an fqdn as the bind address in the config to make sure the service
    is reachable no matter the type of network used.
