Hook requires manual interaction because ip violates uniqueness

[Vern Hart]

I've seen this happen multiple times with hacluster as a subordinate to multiple charms.

cs:~openstack-charmers-next/hacluster-65
juju 2.4.0
ubuntu 18.04.1
crmsh 3.0.1-3ubuntu1

The hacluster charm will be in an error state saying:

    hook failed: "ha-relation-changed"

When manually running the hook with debug-hooks I get an interactive prompt:

    <gents/unit-hacluster-ceph-radosgw-2/charm# hooks/ha-relation-changed
    active
    WARNING: Resources res_cephrg_eth0_vip,res_cephrg_eth2_vip violate uniqueness for parameter "ip": "172.22.28.137"

After answering "y" to the question, it completes without error and the charm transitions to active/idle.

This is due to inconsistent interface ordering across the units in the cluster; this is a dupe of bug 1727824
