In scope of https://github.com/mongodb/mongo-java-driver/pull/1214, we added logging for server detection. A new logging component was added with the suffix DefaultClusterFactory. This goes against existing practice of naming loggers based on abstractions that user's understand, rather than internal class names that may change over time.
We should use a different logger name for this functionality. I suggest client, as that is one that is already used for a similar purpose (to log MongoClient creation parameters).
