Description

~~HDFS-11530~~ has made it configurable to use DFSNetworkTopology, and still uses NetworkTopology as default.

Given the stress testing in HDFS-11923 which shows the correctness of DFSNetworkTopology, and the performance testing in ~~HDFS-11535~~ which shows how DFSNetworkTopology can outperform NetworkTopology. I think we are at the point where I can and should enable DFSNetworkTopology as default.

Any comments/thoughts are more than welcome!
