The monitoring connections and default connection handshake should no longer call buildInfo. The only required information from the buildInfo is the version, which we should replace with wireVersion from isMaster.

Update the command.Handshake type to no longer call buildInfo nor getLastError.

Update the max staleness feature to use wireVersion instead of the server version.

Remove the buildInfo related information from description.Server and remove result.BuildInfo as a parameter to description.NewServer.
