A KubernetesProxyActor proxies all requests from the Guestbook actors to Kubernetes.
A KubernetesProxyActor proxies all requests from the Guestbook actors to Kubernetes. It is a slim wrapper
around the skuber API, and enables sharing of skuber resources (e.g. underlying WS client
connections, watches etc.) by all calling actors.
It supports request messages to create/delete/get Service and Replication Controller
resources on Kubernetes.
For each of the above the actor simply creates and invokes a skuber request, and pipes the
(future) response back to a result handler actor specified in the request message.
It also supports a WatchReplicationController message that puts a reactive watch on a specified
replication controller that forwards any updates received via the watch to one or more
a specified actor. Multiple actors may watch the same controller - they reuse the same underlying watch.
These watches are used by ScalerActor for monitoring the progress of scaling up/down of
Guestbook services on the cluster.
