Listing out the behaviour found in testing, when policy is disable on the VMI where floating IP is associated. If needed, this can be mentioned in release note.

steps:
1. connect VN2 and VN3 with any-any policy
2. associate FIP from VN1 to VM in VN2
3. send/recv traffic to/from FIP works in this case.

1. create 2 VMs sender and receiver.
2. associate FIP to receiver VM and remove SG
3. able to receive traffic from FIP subnet to FIP.
