[Request] Libreswan plugin for Network Manager

Hello!

I have the need to use Libreswan instead of strongswan to connect to an IPSec IKEv1 XAuth VPN in main mode without a group. Thing is strongswan doesn't support this configuration, so I explicitally need it. Nonetheless, libreswan is as developed as strongswan and it's widely used.

using config files in /etc (ipsec.conf and .secrets) it's possible to correctly configure ipsec/libreswan, but needlessly to say, having the possibility to manage it via a GUI is 100 times better (and easier for "normal" users).

In the current repositories (Zesty) I only found the libreswan's ipsec binaries (package libreswan), but not the network manager plugin (sources are available on github).

I've tried to compile them, but I'm afraid they use a different path pattern than Ubuntu, so without making changes it's not possible to succesfully install it from sources.

Thanks
