Change Details

Part of dbctl's functionality is a `min_replicas` field for each database section, that ensures a minimum number of non-master replicas are always pooled for it -- a `config commit` command will exit with error if there aren't enough replicas pooled. Assuming that this is a useful thing to enforce, DBAs should pick values for sections and configure them with e.g. `dbctl -s eqiad section s3 edit`.
