AccessLogPolicy does not follow Policy Attachment (GEP-713) for conflicting policies

[mikhail-aws]

AccessLogPolicy CRD allows to create multiple k8s resources with same TargetRef. We use multiple policies to create different kind of subscriptions like Cloudwatch, Firehose, etc. Each creates new k8s resource.

But it contradicts GEP-713 spec for conflicting policies. We implemented AccessLogPolicy with GEP in mind. GEP says that only one policy of particular type (CRD) should be valid, others should be marked as conflicting.

I think we should refactor CRD. CRD's Spec should include list of subscriptions and their types, rather than creating multiple k8s resources for each subscription.
