can we support the addition of labels as a feature to trigger?

[borisivan]

Given that the logic is probably very similar, can we support the PR build to occur on the addition of a label? That event is sent from GH, but I don't know of any plugins that allow the build to occur when it receives that event.

It would seem that it would be pretty similar to https://github.com/jenkinsci/github-pr-comment-build-plugin/blob/master/src/main/java/com/adobe/jenkins/github_pr_comment_build/IssueCommentGHEventSubscriber.java but just subscribing to a different event action. (created: label, I think)

I'm mentioning this here because it really does seem related, and also makes things foolproof. When users need to type a certain phrase, typos can be a fact of life. Adding one (or more) of a specific predefined label removes some of that concern, and is a great way to differentiate PRs without needing to parse all the (potentially many!) comments, etc. etc.

This does seem related to me, perhaps the plugin should have been called "pr-change-build" :) I don't have the time to add this, but I welcome PRs and can get it released pretty quickly if you were to add the functionality.

Note, this would look very similar to what was added for reviews: eda2dbd
