remove peer endpoint

in my case the reason is not exactly being able to remove the endpoint,
but rather being able to setup a peer without endpoint, so that only the
endpoint needs to be setup later.
All keys for interface and peer are configured via "wg" standard config
file, so that the interface can be brought up at boot time.
But when having to use a to be resolved host name as endpoint, then the
boot process blocks for around a minute in case no network (incl. DNS)
is available. At least when running systemd reading
/etc/network/interfaces. I'm not using systemd builtin wg support.
There is of course the possibility to bring up the wg-* interfaces later
altogether. But the easiest way for me was to use a local endpoint IP
(127.0.1.1) address, and then use up/down scripts triggered on LAN/WLAN
up/down, which then only resolve the endpoint host name and set via wg
the resolved IP of that.
This way I'm also able to use several hostnames from different DynDNS
providers, in case one service provider is down, which wg as far as I
know doesn't currently support.
1.) resolve first host name
2.) set endpoint IP on peer
3.) ping into tunnel to see if it is working
4.) if not working, then try next host name
