As per conclusion in T188244#4089807, the goal of this task is to create a Gerrit newcomer bot that does two things:
- Add a reviewer ("first-time-contributor") to a patch submitted by a first time contributor and upload a welcome message in a comment
- Add contributors who have started contributing in the last three months with five patches open still to a group called "Newcomers."
That way this bot would help us in two ways: a) provides a solution to welcome newcomers to Gerrit and b) a process to query newcomer patches
Work in progress
