The original module settings were triggered by enable_vpn_tunnel which was not in line with the VPC peering or TGW peering attachment naming. In an effort to simplify and standardize the variable 'enable_vpn_tunnel' was changed to 'enable_vpn_peering'. Additionally, this variable now can enable or disable the VPN gateway itself entirely, whereas previously the VPN gateway was always created even if no tunnels were created.
