BREAKING CHANGES

• aws-cloudformation: this changes the type of the role property in CFN CodePipeline Actions
  from Role to IRole. This is needed to use imported Roles when creating Actions.
• aws-codebuild: this changes the API of CodeBuild's GitHub and BitBucket Sources
  to take an owner/repo pair instead of an entire cloneUrl,
  to make it consistent with the GitHubSourceAction in the CodePipeline package. Also adds handling the reportBuildStatus and insecureSsl Source properties.
• codebuild: the includeBuildID property of
  S3BucketBuildArtifacts was renamed to includeBuildId (note the
  lower-case trailing d).
