Public bug reported:

Neutron reset enable_snat on router-gateway-clear but not on router-
gateway-set which implies inconsistent behavior:


# pub1, pub2 are external networks and router1 is a router

(neutron) router-gateway-set router1 pub1 --disable-snat
Set gateway for router router
(neutron) router-show router1 -c external_gateway_info
