schema: remove invalid top-level keys

The "azurestack", "digitalocean", and "exoscale" keys are all image
artifacts that go under the `images` key. So they shouldn't be listed
as optional entries in the top-level dict.

Remove those until we actually have support for uploading to those
clouds (though e.g. azurestack is clearly one to which that will never
apply).
