k8s cloud name can't start with a number

[Adam Israel]

Juju version: 2.7.1-disco-amd64

If I try to bootstrap a k8s cloud that begins with a number, it fails saying the credential name is not valid.

Steps to reproduce:

$ microk8s.config|juju add-k8s 1234-5678-2345-k8s --client
k8s substrate "microk8s/localhost" added as cloud "1234-5678-2345-k8s".
You can now bootstrap to this cloud by running 'juju bootstrap 1234-5678-2345-k8s'.

$ juju bootstrap 1234-5678-2345-k8s
ERROR credential name "1234-5678-2345-k8s" not valid

If I append an alphabetical character to the cloud name, the bootstrap will succeed.

Yes, this is a requirement in the Juju names standards where we don't allow things to start with a number as it messes up meaningful sorting and such.

The messaging should be more clear about what the name error is though.
