codepipeline: GitHubSourceAction should allow setup without polling or webhook

codepipeline.GitHubSourceAction takes a ‘pollForSourceChanges’ setting. If it is true, codepipeline will poll github for changes. If it is false, then cdk will automatically create a webhook and configure the pipeline use it as a trigger.

This is almost always the right thing to do.

But if you want to trigger a pipeline on a schedule, it would be great to be able to create a pipeline with both of these triggers disable.

There is a workaround to achieve this:

new codepipeline.GitHubSourceAction(this, construct_base_name + 'GitHubSource', {
    ... other settings ...
    // this is needed to prevent webhook creation, but we'll disable it later
    pollForSourceChanges: true
})

const cfnPipeline = pipeline.node.findChild('Resource') as codepipeline.CfnPipeline  		      cfnPipeline.addPropertyOverride('Stages.0.Actions.0.Configuration.PollForSourceChanges', false)

What’s wrong with making this option visible? I think it’s a perfectly viable option for people. We should obvsiouly default to the preferred option, but I don’t see any reason to be opinionated about which options are more “visible” as long as the API is clear

I’m also interested in this. We have some pipelines that only trigger on a schedule.
