yamux: disable yamux keep alive in server channel

yamux client runs in the proxy side, sometimes the client is handling other requests and it's not able to response to the ping sent by the server and the communication is closed. To avoid IO timeouts in the communication between agent and proxy, keep alive should be disabled. fixes kata-containers/proxy#70 fixes kata-containers#231 Signed-off-by: Julio Montes <[email protected]>
