AWS CodePipeline Executions Support Push Events from AWS CodeCommit

AWS CodePipeline can now execute pipelines in response to push-based triggers from AWS CodeCommit. Previously, CodePipeline checked CodeCommit periodically to see if there was a change. Now, CodeCommit will send an Amazon CloudWatch Event when a change is committed to trigger a pipeline execution in CodePipeline.
