This commit introduces the wireguard.Enpoint struct.
It encapsulates a DN name with port and a net.UPDAddr.
The fields are private and only accessible over exported Methods
to avoid accidental modification.
Also iptables.GetProtocol is improved to avoid ipv4 rules being applied
by `ip6tables`.

Remove wireguard.Enpoint struct and use net.UDPAddr for the resolved
endpoint and addr string (dnsanme:port) if a DN was supplied.

This commit introduces the usage of wgctrl.

Users can specify IPs with the annotation "allowed-location-ips".
It makes no difference which node of a location is annotated.
The IP should be routable from the particular location, e.g. a printer in
the same LAN.
This way these IPs become routable from other location.

This commit adds support for defining preshared keys when declaring a
new Peer CRD. This preshared key will be used whenever the nodes in the
Kilo mesh communicate with that peer.

We need to defensively deduplicate peer allowed IPs.
If two peers claim the same IP, the WireGuard configuration
could flap, causing the interface to churn.
This commit adds several output options to the `showconf` command of the
`kgctl` binary:
* `--as-peer`: this can be used to generate a peer configuration, which
can be used to configure the selected resource as a peer of another
WireGuard interface
* `--output`: this can be used to select the desired output format of
the peer resource, available options are: WireGuard, YAML, and JSON.
