      When redis-cli received ASK, it used string matching wrong and didn't
      handle it.
      
      When we access a slot which is in migrating state, it maybe
      return ASK. After redirect to the new node, we need send ASKING
      command before retry the command.  In this PR after redis-cli receives
      ASK, we send a ASKING command before send the origin command
      after reconnecting.
      
      Other changes:
      * Make redis-cli -u and -c (unix socket and cluster mode) incompatible
        with one another.
      * When send command fails, we avoid the 2nd reconnect retry and just
        print the error info. Users will decide how to do next.
        See #9277.
      * Add a test faking two redis nodes in TCL to just send ASK and OK in
        redis protocol to test ASK behavior.
