This adds support for `averageValue` for the `request-per-second` metric
based on Ingress Objects. This is only supported from Kubernetes
`>=v1.14` (https://github.com/kubernetes/kubernetes/pull/72872).
When defining the HPA with `autoscaling/v2beta1` you still need to
define `targetValue` even though it won't be used when `averageValue` is
set. Once we default to `autoscaling/v2beta2` this akward API will be
gone.

* Look at total replicas instead of readyReplicas
In cases where replicas take a bit of time to get ready, the Stackset Controller just keeps on scaling. To avoid this issue,
using the total replicas instead of replicas that are ready.
