    CLOUDSTACK-9470: [BLOCKER] Fix for test_network_acl, SshHelper

    ## Problem
    In a Vmware environment, running `test_network_acl` we examined why sometimes it failed
and sometimes it passed. It was discovered that issue was on `VmwareResource`:
    private int findRouterEthDeviceIndex(String domrName, String routerIp, String mac) throws
Exception {
            VmwareManager mgr = getServiceContext().getStockObject(VmwareManager.CONTEXT_STOCK_NAME);
  "findRouterEthDeviceIndex. mac: " + mac);
            // TODO : this is a temporary very inefficient solution, will refactor it later
            Pair<Boolean, String> result = SshHelper.sshExecute(routerIp, DefaultDomRSshPort,
"root", mgr.getSystemVMKeyFile(), null, "ls /proc/sys/net/ipv4/conf");
    Command sent to router returned a pair which its first parameter was always true but second
parameter sometimes it was null and sometimes the correct output for given command.
    ## Solution
    Examining `SshHelper` we discovered that cases in which second parameter in result was
null, didn't consume stdout properly
