This test triggers failovers on all the shards. When it runs in the sharding_auto_bootstrap (i.e. config_shard) suite, one of the shards is the config server. SERVER-108543 made commands against config.shards have maxTimeMS of 5 seconds, so the failover can now lead to a NetworkInterfaceExceededTimeLimit error like in BF-39515. The moveCollection thread here should retry the command on a NetworkInterfaceExceededTimeLimit error as well.
