preWarmConnectionPool() is ran during the mongos main startup, and it is ultimately a best-effort. However, failures when reading the list of shards from the configsvr will cause preWarmConnectionPool to fail, which results in mongos exiting with an error code 5 (ExitCode::shardingError)
Similarly to SERVER-62036, we should also make failures on preWarmConnectionPool() not end the process
