Currently, the tablet repair scheduler repairs all replicas of a tablet. It does not support hosts or DCs selection. It should be enough for most cases. However, users might still want to limit the repair to certain hosts or DCs in production. https://github.com/scylladb/scylladb/pull/21985 added the preparation work to add the config options for the selection. This patch adds the hosts or DCs selection support.
Fixes https://github.com/scylladb/scylladb/issues/22417
New feature. No backport is needed.
