MockSystemReader.MockConfig is a StoredConfig and is also used by tests for dfs based storage. Hence remove this leaky abstraction. This implies we always use the fallback FileStoreAttributes which means a config file modification is considered racy within the first 2 seconds. This should not be an issue since typically configs change rarely and re-reading a config within the racy period is relatively cheap since configs are small.
