Expose divisor setting in helm

[lukidzi]

Description

We set GOMAXPROCSand GOMEMLIMIT and some user might want to configure for them divisor.
We should expose the option to configure it

            - name: GOMEMLIMIT
              valueFrom:
                resourceFieldRef:
                  containerName: control-plane
                  resource: limits.memory
                  divisor: "1"
            - name: GOMAXPROCS
              valueFrom:
                resourceFieldRef:
                  containerName: control-plane
                  resource: limits.cpu
                  divisor: "1"

By default we should set it to 1

i'm also having an issue with argocd diffing on the divisor because there's no default set for it.

                 resourceFieldRef:
                   containerName: control-plane
-                  divisor: '0'
                   resource: limits.memory
             - name: GOMAXPROCS
                 resourceFieldRef:
                   containerName: control-plane
-                  divisor: '0'
                   resource: limits.cpu
           image: >-

similar issue as cilium/cilium#30634?

For anyone following along, workaround in argo is like this

  ignoreDifferences:
    - group: apps
      kind: Deployment
      jqPathExpressions:
        - '.spec.template.spec.containers[0].env[]?.valueFrom.resourceFieldRef.divisor'
