Build Event Json includes Environment Variables
Description
I use build events to track the status of various stages of builds across many projects. While it's really useful to have these automatically fired to a webhook url, it would be far more useful for our needs if the JSON sent to this endpoint also included the environment variables in the build. I specifically refer to custom variables (set through settings > variables).
I appreciate this is potentially problematic where people are using these for secure variables / passwords. So it would require a different kind of variable to be introduced which could safely be passed a long with a web hook. However, I feel the benefit gained by being able to access the whole context of a build would make it worth the effort of doing this.
