We add support for `--ignore-dead-nodes` in `raft_removenode` and `--ignore-dead-nodes-for-replace` in `raft_replace`. For now, we allow passing only host ids of the ignored nodes. Supporting IPs is currently impossible because `raft_address_map` doesn't provide a mapping from IP to a host id. The main steps of the implementation are as follows: - add the `ignore_nodes` column to `system.topology`, - set the `ignore_nodes` value of the topology mutation in `raft_removenode` and `raft_replace`, - extend `service::request_param` with alternative types that allow storing a set of ids of the ignored nodes, - load `ignore_nodes` from `system.topology` into `request_param` in `system_keyspace::load_topology_state`, - add `ignore_nodes` to `exclude_nodes` in `topology_coordinator::exec_global_command`, - pass `ignore_nodes` to `replace_with_repair` and `remove_with_repair` in `storage_service::raft_topology_cmd_handler`. Additionally, we add `test_raft_ignore_nodes.py` with two tests that verify the added changes.

Scylla developer documentation
This folder contains developer-oriented documentation concerning the ScyllaDB codebase. We also have a wiki, which contains additional developer-oriented documentation. There is currently no clear definition of what goes where, so when looking for something be sure to check both.
Seastar documentation can be found here.
User documentation can be found on docs.scylladb.com
