We modify `ScyllaCluster.server_start` so that it changes seeds of the starting node to all currently running nodes. This allows writing tests like ```python s1 = await manager.server_add(start=False) await manager.server_add() await manager.server_start(s1.server_id) ``` However, it disallows writing tests that start multiple clusters. To fix this, we add the `seeds` parameter to `server_start`. We also improve the logic in `ScyllaCluster.add_server` to allow writing tests like ```python await manager.server_add(expected_error="...") await manager.server_add() ``` This PR only adds improvements to the `test.py` framework, no need to backport it.

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.
