Bug Description

After MAAS is setup, juju fails with

2021-06-05-15:02:27 root DEBUG [localhost]: juju enable-ha -c foundations-maas
2021-06-05-15:02:28 root ERROR [localhost] Command failed: juju enable-ha -c foundations-maas
2021-06-05-15:02:28 root ERROR [localhost] STDOUT follows:
b''
2021-06-05-15:02:28 root ERROR [localhost] STDERR follows:
ERROR juju-ha-space is not set and a unique usable address was not found for machines: 0
run "juju controller-config juju-ha-space=<name>" to set a space for Mongo peer communication

It seems the reason is two IPs assigned to the same interface as seen in

This is the commissioning data from one of the VMs that had multiple AUTO IPs:

So it got two IPs during commissioning. We should be able to work around this, so that we don't create any aliases during commissioning, but it would be interesting to figure out why the machine got two IPs in the first place.

Looking at tcpdump during commissioning, both DHCP servers in the HA deployment offer an address, which the host accepts.
