cloud-init: fix strict mode, ensure cloud-init only runs on positive id

[raharper]

cloud-init still runs when no local datasource is present unless we ignore maybe datasources (ones that may be populated later during boot). Core uses strict mode which requires positive identification or cloud-init doesn't run.

Does this do the right thing in an actual cloud case?

[smoser]

In short, yes. It does the right thing for as many cases as it can.
In cases where it cannot identify the cloud provider, cloud-init will be disabled. That is not the ideal solution but it does the best it can do with the information available and without polling network resources.

Is there a reason that this can't be processed? Waiting on anything from us? thanks!

Looks good to me based on provided feedback.
