Add support to Delete a Pull Request

Issue Summary

We would like to be able to delete pull requests so they are fully removed from the repository.

Workaround

1. If you are a paying customer, you can reach out support team and request deleting a pull request.
2. If you don't mind the pull requests remain in your repository, you can decline them.

IMPORTANT:

If you are looking to delete a pull request because sensitive information was published in a pull request, please read this article. It is important to realize that deleting a pull request will not remove sensitive data from your repository.
