Ignore CRD status diff by default

[alexmt]

Summary

For some reason some Helm charts include CRD definitions with an empty status. Examples:

• https://github.com/helm/charts/blob/master/incubator/jenkins-operator/CRD/jenkins_v1alpha2_jenkinsinstance.yaml#L158
• https://github.com/helm/charts/blob/master/incubator/sparkoperator/templates/crds.yaml#L3971
• https://github.com/banzaicloud/logging-operator/blob/master/charts/logging-operator/crds/logging.banzaicloud.io_flows.yaml#L770

I suspect this is required to CRD delete conditions on every kubectl apply. The status is immediately modified by Kubernetes and Argo CD detecting it as a deviation ( #3391, #2239).

Motivation

The workaround is to configure Argo CD to ignore CRD status. Because an issue is happening for multiple users lets include that configuration by default.

Docs say this should be happening already ?

  resource.compareoptions: |
    # disables status field diffing in specified resource types
    # 'crd' - CustomResourceDefinition-s (default)
    # 'all' - all resources
    # 'none' - disabled
    ignoreResourceStatusField: crd
