Auto assign new issues to users from a pool to perform triaging
Related to https://gitlab.com/gitlab-org/gitlab-ce/issues/17693
We get dozens of new issues on https://gitlab.com/gitlab-org/gitlab-ce/issues every day, and it would be a full time job for someone to triage all of those by themselves. Triaging here can mean assigning labels, mentioning relevant people, asking for more information, closing as duplicate, or closing for other reasons.
We should be able to create a pool of people who will get assigned new issues in a round robin fashion automatically, so that every one of them has only N/M issues to triage every morning, where N is the number of new issues per day, and M the number of people in the pool.
With N at around 40, and M which we could set at 20, that's only 2 issues per person! That shouldn't take up more than 10 minutes of anyone's morning.
