Stack apply fails for stacks containing both CRD + instances of that custom resource

[SpComb]

The K8s::Stack#apply => client.get_resources attempts to perform API discovery for all stack resources before starting the POST the resources. This fails for custom resources associated with CRDs in the same stack because the CRDs are not defined yet, so the API discovery returns a HTTP 404.

The API discovery at this point should just ignore the 404 errors, and assume that those resources will not exist yet.
