Support filterPolicies

[Jacob Ester]

It seems that one is not able to use filter policys like

functions:
    function:
...
        events:
            - pubSub:
                topic:
                    name: 'TopicName'
                    arn: 'arn:aws:sns:eu-central-1:account:TopicName'
                queue: true
                filterPolicy:
                    pets:
                        - cats
                        - dogs  

Queue is generated corrently and added to topic, but no filter are set.
