Profile update with security group changes only should not recreate network

[Duc Truong]

When updating a cluster profile with changes to the port security groups only, the network should not be deleted and recreated. Instead, the security group changes should be applied to the existing port.

E.g. old profile:

type: os.nova.server
version: 1.0
properties:
  flavor: 1
  image: "cirros-0.5.1-x86_64-disk"
  networks:
   - network: private
     security_groups:
        - default
  metadata:
    test_key: test_value

new profile:

type: os.nova.server
version: 1.0
properties:
  flavor: 1
  image: "cirros-0.5.1-x86_64-disk"
  networks:
   - network: private
     security_groups:
        - default
        - blah
  metadata:
    test_key: test_value
