Add more logging for raft-based topology operations in INFO and DEBUG
levels.
Improve the existing logging, adding more details.
Fix a FIXME in test_coordinator_queue_management (by readding a log
message that was removed in the past -- probably by accident -- and
properly awaiting for it to appear in test).
Enable group0_state_machine logging at TRACE level in tests. These logs
are relatively rare (group 0 commands are used for metadata operations)
and relatively small, mostly consist of printing `system.group0_history`
mutation in the applied command, for example:
```
TRACE 2024-08-02 18:47:12,238 [shard 0: gms] group0_raft_sm - apply() is called with 1 commands
TRACE 2024-08-02 18:47:12,238 [shard 0: gms] group0_raft_sm - cmd: prev_state_id: optional(dd9d47c6-50ee-11ef-d77f-500b8e1edde3), new_state_id: dd9ea5c6-50ee-11ef-ae64-dfbcd08d72c3, creator_addr: 127.219.233.1, creator_id: 02679305-b9d1-41ef-866d-d69be156c981

```
note that the mutation contains a human-readable description of the
command -- like "create system_distributed keyspace" above.
These logs might help debugging various issues (e.g. when `apply` hangs
waiting for read_apply mutex, or takes too long to apply a command).
