specifying configData in the policy-controller helm chart gives a values validation error

[steinwelberg]

Description

When upgrading the policy-controller Helm chart (from version 0.8.0 to 0.8.1) with the following values:

webhook:
  replicaCount: 3
  securityContext:
    enabled: true
    runAsUser: 1000
  configData:
    no-match-policy: warn
serviceMonitor:
  enabled: true

this will result in the following error:

  Warning  UpgradeFailed  30s  helm-controller  Helm upgrade failed for release infra-cosign/policy-controller with chart [email protected]: values don't meet the specifications of the schema(s) in the following chart(s):
policy-controller:
- webhook.configData: Additional property no-match-policy is not allowed

Most likely this is caused by the upated helm values schema which is quite restrictive as it specifies the "additionalProperties": false, property. Not only on the configData object, but also on the securityContext, customLabels, env, extraArgs all specify this which prevent a user to specify custom properties.
