Description

VPN Gateway resource has NAT Rules in Preview, this feature request is to add a new resource to create nat rules as well as an associative resource to link a nat rule to a connection.

It's probably best the resource mimics the equivalent Virtual WAN resource azurerm_vpn_gateway_nat_rule as closely as possible.

Additionally currently, adding NAT rules through the portals to a azurerm_virtual_network_gateway makes following applies to fail do to existing NAT rules.
