gce region zone names not respected on bootstrap

[Pietro Pasotti]

juju default-region google europe-west4
juju add-credential google
when prompted select region [any region, credential is not region specific]: enter europe-west4.

juju bootstrap google gce gives me output:

Creating Juju controller "gce" on google/us-east1

I think juju should complain (warn, at least) if `europe-west4` is not a known region.
Also, probably refuse to bootstrap if the requested region name cannot be respected.

It doesn't appear that the GCE provider makes any attempt to honour this argument.

The logic there has some superfluous layers that need to be flattened, which we should address along with this issue.

[Joseph Phillips (manadart)]

Actually, the argument I was looking at is not used, but is taken from the cloud definition.

If am using 3.4 here...

Juju will prevent you from setting an invalid region with the default-region command.

Once set, "juju show-cloud google" gives me:

defined: public
type: gce
description: Google Cloud Platform
auth-types: [jsonfile, oauth2]
default-region: europe-west4
credential-count: 1
...

Then bootstrapping does create an instance in that region.

What version of Juju are you using?

I'm on 3.4.2, I think I didn't upgrade since this occurred
