[stable/polaris] Chart should not depend upon .Capabilities.APIVersions

[Erik Lund]

Is your feature request related to a problem? Please describe.
In a GitOps setup like ArgoCD you want to be in control of what is deployed. Using .Capabilities.APIVersions only reflects the version at the time of deployment. If cert-manager is upgraded then the deployed Polaris will not be updated.

Furthermore, ArgoCD does not support .Capabilities.APIVersions.Has for cert-manager.io APIs.

Describe the solution you'd like
Add new option to overrule the cert-manager API version.
For example

webhook:
  certManager:
    apiVersion: "cert-manager.io/v1" 

and update webhook.cert.yaml to use this new field if configured.

Describe alternatives you've considered
Remove all requirments to use helm install for deployment of any of the FairwindsOps charts.

Additional context
GitOps, ArgoCD, less dependencies to helm hooks

This would be a great addition. We already do this in a few other charts. Do you want to add it or shall I go ahead and do the PR?

[Erik Lund]

Please go ahead. That way it will be aligned with your other charts.
