Userdata to display static NAT as public ip instead of VR ip (#3862)
* Userdata to display static NAT as public ip instead of VR ip

If static nat is enabled on VM then metadata service should return
the static nat instead of gateway IP.
If static not is not enabled then it should return the gateway IP
as the public IP

Test results:

Step to reproduce:

1. Create a vm
2. Ssh to vm.
3. Run the below command inside the vm
wget http://<VR public ip>/latest/meta-data/public-ipv4

Note down the output of the above command
4. Now acquire a new public and enable static NAT on that IP to this vm
5. Now run the same command mentioned above in the VM
This should display the static NAT ip instead of VR public IP

Output:

Before enabling static nat

wget http://10.10.10.40/latest/meta-data/public-ipv4
$ cat public-ipv4
10.10.10.29

After enabling static nat

wget http://10.10.10.40/latest/meta-data/public-ipv4
$ cat public-ipv4
10.11.10.30

* server: apply vm user data when release a public ip
