agent: disable yamux keep alive

We don't know how much time a sandbox can be paused, hence connection write timeout should be disabled to don't close the connection while the sandbox is paused. The same issue has been fixed in kata-proxy, for katabuiltin proxy, it also needs this fix. fixes kata-containers#294 Signed-off-by: fupan <[email protected]>
