feat: separate podlabels in controller-manager and audit deployment

[robertbublik]

What this PR does / why we need it:

We want to introduce new labels across our infrastructure and validate them using the K8sRequiredLabels policy. Depending on its workload each pod will receive a different workload label which is then used to enrich metrics collected from it. The Gatekeeper Helm chart doesn't allow setting separate labels for the controller manager pod and audit pod which will break our idea.

Special notes for your reviewer:

I was following the PR below to apply the changes here.

• https://github.com/open-policy-agent/gatekeeper/pull/1126

I had to remove {{- include "gatekeeper.podLabels" . | nindent 8 }} across all jobs since it's removed from the helpers.tpl file.
