Add a Configuration field to PolicyReport

[anusha94]

Some scale issues identified for PolicyReport can be found in this thread - https://github.com/open-policy-agent/gatekeeper/issues/2394

One option to tackle this issue is for the PolicyReport API to provide some kind of contract between PolicyReport generators and consumers. The proposal here is to add a Configuration field to the API -

configuration:
  limits:
    maxResults: 100
    statusFilter: ["FAIL", "WARN"]

This defines the max number of reports that will be stored. Also, provide a way to store only reports that the user may be interested in - the statusFilter allows to filter based on different status values - pass, fail, error, warn, skip. The setting of these values should be exposed via the PolicyReport generator (for example, policy engines). The PolicyReport API should provide sane defaults for these fields
