snat vns created (with name svc-snat-si_* ) are not deleted on deleting external gateway config

[Vedamurthy Joshi]

R1.10 34

Each time a router with gateway is configured, we are creating a new VN (by name svc-snat-si_<UUID>), but we dont delete them on
clearing the gateway config.

Over time as one keeps doing this, a number of such vns would clutter the VN output

It would be nice to automatically delete such VNs

Release-note :
============
VNs with name svc-snat-si_<UUID> which are created dynamically on configuring SNAT external gateways are not automatically deleted on removing the external gateway or router
