When the topology coordinator is shut down while doing a long-running
operation, the current operation might throw a raft::request_aborted
exception. This is not a critical issue and should not be logged with
ERROR verbosity level.
Make sure that all the try..catch blocks in the topology coordinator
which:
- May try to acquire a new group0 guard in the `try` part
- Have a `catch (...)` block that print an ERROR-level message
...have a pass-through `catch (raft::request_aborted&)` block which does
not log the exception.
