Currently, all 3 implementations of `StorageEngine::Factory` use `kWiredTigerEngineName` to specify the name of the serverStatus section for the storage engine. However, this is a bit clunky since `kWiredTigerEngineName` is also used to specify the config file section name for `WiredTigerKVEngine`, similar to how ‘inMemory’ is used for `InMemoryFactory` and `queryable_wt` for `QueryableWtFactory`. This caused a bit of confusion for me. Fixing it by using a separate string literal for `WiredTigerServerStatusSection` to decouple it from the string literals used for the config file.
