Title: Added ping buckets 

Draft for ping buckets to select instance based on ping time.
The change is based on https://jira.mongodb.org/browse/JAVA-428 proposal :
instance are put in exponentially growing buckets and instance selection is done on the fastest non-empty bucket.

NOT properly tested yet, tell me if you are interested in more tests.

Is useful onyl when connected to a replicaset, I don"t know yet what to do when connected to several mongos.
