Create logger per class/package

For 3.0, we are going to standardize on new prefixes for all loggers:

• org.mongodb.driver
• org.bson

Logger names are:

• org.mongodb.driver.management
• org.mongodb.driver.cluster
• org.mongodb.driver.cluster.monitor
• org.mongodb.driver.connection
• org.mongodb.driver.session
• org.mongodb.driver.operation
• org.mongodb.driver.protocol
• org.mongodb.driver.uri
• org.bson.reader
• org.bson.writer
• org.bson.ObjectId
