It is unsafe to restrict the sync nodes for repair to the source data center if it has too low replication factor in network_topology_replication_strategy, or if other nodes in that DC are ignored. Also, this change restricts the usage of source_dc to `network_topology` and `everywhere_topology` strategies, as with simple replication strategy there is no guarantee that there would be any more replicas in that data center. Fixes #16826 Reproducer submitted as https://github.com/scylladb/scylla-dtest/pull/3865 It fails without this fix and passes with it. * Requires backport to live versions. Issue hit in the filed with 2022.2.14 Closes scylladb/scylladb#16827 * github.com:scylladb/scylladb: repair: do_rebuild_replace_with_repair: use source_dc only when safe repair: replace_with_repair: pass the replace_node downstream repair: replace_with_repair: pass ignore_nodes as a set of host_id:s repair: replace_rebuild_with_repair: pass ks_erms from caller nodetool: rebuild: add force option Add and use utils::optional_param to pass source_dc

If you can use an existing folder, consider adding your test to it. New folders should be used for new large categories/subsystems, or when the test environment is significantly different from some existing suite, e.g. you plan to start scylladb with different configuration, and you intend to add many tests and would like them to reuse an existing Scylla cluster (clusters can be reused for tests within the same folder).
To add a new folder, create a new directory, and then
copy & edit its suite.ini.
