Support for Github Issues and Comments

[dave-tucker]

It would be awesome for the Github integration to be able to handle issues and comments.

Manipulating CI through comments is one common use case. For example;

• One could set up a pipeline that did not build PR's from the public until a maintainer comments to allow the build.
• One could also manage a whitelist/blacklist of users for the aforementioned filtering this way too
• Another useful feature is to trigger stop/start/rebuild of PR's from a comment

In addition to comments on PRs, having access to issues would be necessary to create an automated triaging pipeline based on the contents of bug-reports. For example, you could run a container that analyses the contents of a bug report and suggests possible fixes and/or related issues!
