   @yvsubhash given this has introduced a regressions in snat IP allocation I'm consider this
for a revert unless you can help with a quick fix to unblock other PRs being merged.
   
   The failure found was:
   ```
   test_01_vpc_remote_access_vpn (integration.smoke.test_vpc_vpn.TestVpcRemoteAccessVpn):

   ```
   
   The issue can be reproduced by creating a VPN and deploying a VM on a tier. You'll still
see the SNAT ip marked as Allocating and this causes creation of VPN to fail.
