Rename the attributes of IsMaster, ServerDescription, TopologyDescription, and
TopologySettings from "set_name" to "replica_set_name" for greater clarity.
The Server Discovery And Monitoring Spec has replaced the term "cluster"
with "topology", since "cluster" in MongoDB terminology should be reserved
for sharded clusters. "Topology" describes a single server, replica set, or a
set of mongoses.
The previous commit replaced "cluster" with "topology" in file names. Here
I replace the term in class and variable names.

The next commit will replace "Cluster" names with "Topology".
Replace MongoClient with an implementation that relies on Cluster and Server. The new MongoClient takes over MongoReplicaSetClient's responsibilities.
Authentication, secondary-pinning, and Mongos high-availability are broken and will be reimplemented in a future commit. RS tests are temporarily disabled.
