v2.0.0-alpha.6

⚠ BREAKING CHANGES TO EXPERIMENTAL FEATURES

• ecs-patterns: ** the desiredCount property stored on the above constructs will be optional, allowing them to be undefined. This is enabled through the @aws-cdk/aws-ecs-patterns:removeDefaultDesiredCount feature flag. We would recommend all aws-cdk users to set the REMOVE_DEFAULT_DESIRED_COUNT flag to true for all of their existing applications.
