"drop" config should be an array

When creating CLF with "drop" log record functionality:
~~~
cat clf.yaml 
apiVersion: logging.openshift.io/v1
kind: ClusterLogForwarder
metadata:
  name: instance
  namespace: openshift-logging
spec:
  filters:
  - name: important
    type: drop
    drop:
      test:
      - field: .kubernetes.namespace_name
        matches: "^open"
      test:
      - field: .log_type
        matches: "application"
      - field: .kubernetes.pod_name
        notMatches: "my-pod"
  pipelines:
  - name: test 
    filterRefs: ["abc"]
    inputRefs:
    - application
    outputRefs:
    - default
~~~
$ oc create -f clf.yaml 
The ClusterLogForwarder "instance" is invalid: spec.filters[0].drop: Invalid value: "object": spec.filters[0].drop in body must be of type array: "object"

"drop" should be an array and same is correct in the docs.
