Alternator's non-standard "/localnodes" HTTP request returns a list of live nodes on this DC, to consider for load balancing. The returned node addresses should be external IP addresses usable by the clients. Scylla has a configuration parameter - broadcast_rpc_address - which defines for a node an external IP address. If such a configuration exists, we need to use those external IP addresses, not the internal ones. Finding these broadcast_rpc_address of all nodes is easy, because the gossiper already gossips them. This patch also tests the new feature: 1. The existing single-node test is extended to verify that without broadcast_rpc_address we get the usual IP address. 2. A new two-node test is added to check that when broadcast_rpc_address is configured, we get that address and not the usual internal IP addresses. Fixes #18711.

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.
