The sys perf workload mongos_large_catalog_workloads writes up to a million documents into config.chunks, meant to simulate metadata with very many collections. Prior to SERVER-51070, writes against the config server through a mongos would use a maxTimeMS of 30 seconds, and prior to PM-2130, if such writes weren't sent with an explicit write concern, they would use majority with a wtimeout of 30 seconds. Occasionally these timeouts are exceeded on branches that don't include those changes, in particular 4.4 and earlier. This ticket is to track using higher timeouts to avoid failures on those branches.
