    Create default sg rules when create a sg
    
    Sometimes we need to create a default security rule when a new security
    group is created. The following patch facilitates the same. The format
    of default security group rule is
    "ethertype,direction,protocol,port_range_min,port_range_max".
    For example:
    security_group_default_rules=ipv4:ingress:tcp:22:22,ipv4:ingress:tcp:80:80
