Allow adding custom annotations and labels to the k8gb controller (#1704

) I just faced a usecase where I needed to add an istio expection on the k8gb controller via an annotation. However, the chart did not allow it. This PR also allows adding custom labels since this feature may be desired for other usecases. Signed-off-by: Andre Baptista Aguas <[email protected]>
