Wavefront-Proxy service with non ClusterIP type

[vavdoshka]

We want to leverage Wavefront-Proxy in K8s to accept and process the metrics from non-K8s cluster origin, which would require the Proxy Service to be the type of LoadBalancer. Which is currently not possible:

helm/wavefront/templates/proxy-service.yaml

Line 65 in 85f8f35

type: ClusterIP

In addition to this, we would want to have only one proxy Deployment per cluster and use it for both internal K8s metrics traffic and the traffic with different origins external to the K8s cluster. So that means we would need to have two services with different types, one ClusterIP for internal traffic (as is the case now) and one with LoadBalancer type to handle external traffic.

So to sum up I propose to:

• add the possibility to define (enable) an extra service object for Wavefront Proxy with type LoadBalancer.
