Which repository, branch, commit triggered the Bamboo Spec to run

Problem Definition

Basically our concept is to have "Staging" Projects for Plans before merging them to master which would be considered "Production".

Suggested Solution

Have an Event that was triggered and that rest api could look at after the fact.

Why this is important

We need input information on the trigger that started Bamboo Spec. We need to be able to tie a particular run of Bamboo Spec to either a repo and a commit or to the linked repo in Bamboo.
