A mux to a clustered cache is created by specifying one of the endpoints in the cluster. SE.Redis then runs the CLUSTER NODES command to connect to individual nodes of the cluster. The initial connection to discover cluster nodes is not used for any client application commands after the initial discovery. This PR proposes to close this connection after discovery of the nodes in the cluster, which will help to reduce the total number of connections from each of the multiplexer when running at scale.
