Make CloudCustodian policies do an initial resource evaluation

[Richard-Hansen]

CloudCustodian policies do not do an initial evaluation of resources when deployed. We can create a second policy, this one will activate the policy when its created. A little hacky, but there don't seem to be other supported approaches.

policies:
  - name: trigger-config-eval
    resource: aws.config-rule
    filters:
      - ConfigRuleName: "my-config-rule"
    actions:
      - type: evaluate
