Change the order of setup-cni.sh parameters

Change the order of setup-cni.sh parameters

To facilitate the manual installation of various CNIs
by using setup-cni.sh, the order of setup-cni.sh parameters
is changed as:
1. CNI_TYPE
2. POD_NETWORK_CIDR
3. CLUSTER_IP
4. As-is ...

The reason to do in this way is that the CLUSTER_IP parameter
is only needed by Calico CNI, but the CNI_TYPE and POD_NETWORK_CIDR
is needed by all CNIs when we do it manually (by calling
setup-cni.sh directly).
