Change namespace.yaml path to /opt

[gouyang]

Fixes #944

[eparis]

I think the script looking in /opt needs to be fixed to look somewhere else. In atomic you can't even create /opt...

[gouyang]

There is /opt exists on Atomic host.

$ ls -lsh / | grep opt
   0 lrwxrwxrwx.   1 root root    7 May  4 23:44 opt -> var/opt

It need to adjust on one side. Actually I don't see why it changes the path.

Open kubernetes/kubernetes#25440

[mikedanese]

/opt is a path inside the kube-addon-manager container.

@mikedanese browsing files in https://github.com/kubernetes/kubernetes/blob/master/cluster/saltbase/salt/kube-addons/, /etc/kubernetes and /etc/kubernetes/addons is used there. is it /opt must be used for namespace.yaml?
