ipc.Client.setupIOstreams() needs to check for ClientCache.stopClient requested shutdowns

      Description

      When ClientCache.stopClient() is called to stop the IPC client, if the client
      is blocked spinning due to a connectivity problem, it does not exit until the policy has timed out -so the stopClient() operation can hang for an extended period of time.

      This can surface in the shutdown hook of FileSystem.cache.closeAll()

      Also, Client.stop() is for used in NN switch from Standby to Active, and can therefore have very bad consequences and cause downtime.
