Enhancement: Expose "Subscription Filter Policy" for AWS SNS Topic Subscriptions

[rbwestmoreland]

Enhancement

• Provider: aws
• Resource: aws_sns_topic_subscription

Please expose the "Subscription Filter Policy" feature for the aws_sns_topic_subscription resource.

A subscription filter policy is a simple JSON object that enables your subscriber to receive only the subset of messages it’s actually interested in, as opposed to receiving every single message published to the topic.

When a message is published to the topic, Amazon SNS will attempt to match the incoming message attributes to the subscription attribute that defines a filter policy. If they match, Amazon SNS will then deliver the message to the corresponding subscriber.
