Operator Helm chart: API server port should be configurable

[toms-place]

Our kube-api listens on port 6443 so we need to change the port as well.

Proposed solution: add a kubeAPIServerPort configuration to the helm values.

I guess you mean here:

cloud-on-k8s/deploy/eck-operator/templates/operator-network-policy.yaml

Lines 23 to 27 in 54ec0e3

	- ports:
	- port: 443
	to:
	- ipBlock:
	cidr: "{{ $kubeAPIServerIP }}/32"

?

@barkbay yes, exactly.
