Add-unit with a KVM fails to warn about spaces

[Michael Skalka]

When adding a kvm container unit of an existing service using `juju add-unit <service> --to kvm:<machine>` if there are multiple spaces available on that machine Juju will fail to warn the user and deploy the node resulting in the following error in the machine section of the juju status:

failed to start machine 0/kvm/0 (unable to setup network: no obvious space for container "0/kvm/0", host machine has spaces: "one", "undefined"), retrying in 10s (8 more attempts)

[Richard Harding (rharding)]

We should make this like the lxd code where if you've not used any spaces in the model yet we don't require you to bind endpoints. If you do have spaces work in the model then we require explicit placements to avoid guessing.

I do believe the same thing happens for an lxd container. Rereading this,
it sounds just that Michael would like a deploy time check of this rather
than a provisioning check.
We traditionally haven't done deploy time checks because the machines don't
exist until provisioned but for lxd/kvm:N we know the machine details.

There are edge cases we will want to be careful of. The machine N doesn't
have to be provisioned before you ask for a container, and you might be
mixing multiple locations at the same time (deploy takes -n and --to can be
given a list).

I do think it would be much better user experience, though.

Removing from a milestone as this work will not be done in 2.5 series.
