VPA: Recommender Configuration for containerPolicies

[jklaw90]

Which component are you using?:

/area vertical-pod-autoscaler

Is your feature request designed to solve a problem? If so describe the problem this feature should solve.:
Right now i'd like different recommenders for memory vs cpu which causes us to need multiple CRs.

Describe the solution you'd like.:

spec.recommenders is a list so it should support multiple recommenders but we need to be able to specify them on our container policies like so

spec:
  resourcePolicy:
    containerPolicies:
    - containerName: '*'
      controlledResources:
      - cpu
      recommender: recommender1
    - containerName: 'sidecarxyz'
      controlledResources:
      - memory
      recommender: recommender2
  recommenders:
    - name: recommender1
    - name: recommender2

Describe any alternative solutions you've considered.:

Add an additional VPA cr. For us this would cause the need for a 3rd VPA for a resource.

Right now i'd like different recommenders for memory vs cpu which causes us to need multiple CRs.

Why do you need different recommenders for memory vs cpu? Is that not the problem that needs solving here?
