nixos/patroni: remove raft

- The `services.prometheus.exporters.minio` option has been removed, as it's upstream implementation was broken and unmaintained.

  Minio now has built-in [Prometheus metrics exposure](https://min.io/docs/minio/linux/operations/monitoring/collect-minio-metrics-using-prometheus.html), which can be used instead.

- The `services.patroni.raft` option has been removed, as Raft has been [deprecated by upstream since 3.0.0](https://github.com/patroni/patroni/blob/master/docs/releases.rst#version-300)
