migrate to golang.zx2c4.com/wireguard/wgctrl (#239)
* migrate to golang.zx2c4.com/wireguard/wgctrl

This commit introduces the usage of wgctrl.
It avoids the usage of exec calls of the wg command
and parsing the output of `wg show`.

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

* pkg/*: use wireguard.Enpoint

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`.

cmd/kgctl/main.go: suppress second error message
`cobra` automatically prints and error if `runE` returns an error.
Since we explicitly print the error, we need to silence cobra.

pkg/: FEATURE: support allowed IPs outside a cluster
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.

cmd/kgctl: improve default kubeconfig
This commit adds better handling of the default kubeconfig location in
the kgctl binary for cases where the `$KUBECONFIG` environment variable
is not set. In these cases, kgctl will default to
`$HOME/.kube/config`, putting it in line with tools like `kubectl` and
`kind`.

pkg/k8s/apis: support for preshared keys in peers
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.

pkg: deduplicate peer IP addresses
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.

cmd/kgctl: add output options for showconf
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.
