Anonymization is among the most expensive operations we can perform with extreme potential to impact the database. To mitigate risk we only allow a single anonymization across the entire cluster concurrently. This commit introduces support for `cluster_concurrency 1`. When you set that on a Job it will only allow 1 concurrent execution per cluster.
