Input should be deeply nested inside arrays

[lukehoban]

In the other providers, we deeply nest Input<T> through arrays, such as:

readonly tags?: pulumi.Input<pulumi.Input<string>[]>;

In the Kubernetes provider, we apparently do not, such as:

args?: pulumi.Input<string[]>

This leads to code like this not working as written (and requiring all), while it should not.

                           args: [
                                "/nginx-ingress-controller",
                                pulumi.concat("--default-backend-service=$(POD_NAMESPACE)/",  defaultBackendServiceName),
                                "--ingress-class=" + ingressClass,
                                "--report-node-internal-ip-address",
                            ],
