解決rdo安裝過程中，puppet的timeout相關問題

（一）錯誤記錄檔：
http://storageboy.com/2013/04/25/quick-tip-on-installing-and-running-redhats-openstack-distro/
ERROR : Error during puppet run : err:
/Stage[main]/Packstack::Netns/Exec
[netns_dependecy_install]/returns: change from notrun to 0 failed: Command exceeded timeout at /var/tmp/packstack/f93b67f77de342619ed9805ecc823c8d/modules/packstack/manifests/netns.pp:13

（二）解決方案：

# vim /usr/lib/python2.6/site-packages/packstack/puppet/modules/packstack/manifests/netns.pp

在command => "yum update -y kernel iputils iproute"
上面加一行timeout => 3600，

然後從新執行rdo安裝過程
執行前提先kill掉進程裡面的flock ，puppet，yum進程
