Subject: [PATCH] Add PollForSourceChanges attribute

Explicit turn-off of PollForSourceChanges when github token present, to prevent pipeline being triggered twice (i.e. via webhook and periodic polling).  See here for background: https://docs.aws.amazon.com/codepipeline/latest/userguide/pipelines-webhooks-create.html
