+Git trailer to PR body. It parses the Git log to gather a set of "Authors" and "Reviewers". 
+Some simple string prefix matching is done to find candidates. 
+After entering the pull request number, the script updates the "Reviewers:" trailer accordingly. 
+If the PR body already contains a "Reviewers:" trailer, the script replaces it with the updated list of reviewers.
