  Create Network, Subnet, ext & int
  Create router, add 2 gateway, from 

1. Create internal network/subnet, instance could get IP from dhcp, ping gateway failed.
2. Create a router, add interface to internal network, ping gateway OK. but couldn't get 169.254.169.254, 
    Because metadata agent in Network node couldn't reach, so couldn't trans 169.254.169.254:80 to 9697, see from iptables -t nat => redirect
3. Create external network/subnet, remember subnet should cover your network node, or you need to add route manually, no disable gw, no dhcp
4. set gateway in router, now we can ping external world
5. Add floating IP
6. Add rules in default secure group, TCP 22, ICMP -1 -1, CIRD.
