SERVER-18849 only send wire version for find/getMore commands if config server mode is CSRS

A mongod will return a maxWireVersion of 4 to indicate support for the find and
getMore commands. In constrast, mongos will only return maxWireVersion of 4 if
configured with CSRS, as full find/getMore command support is predicated on
config server as a replica set.
