pkg/iptables: enable simultaneous ipv4 and ipv6
This commit enables simultaneously managing IPv4 and IPv6 iptables
rules. This makes it possible to have peers with IPv6 allowed IPs in an
otherwise IPv4 stack and vice versa.

pkg/iptables: re-organize rules
This commit better organizes the location of iptables rules. This is
made possible by exposing two new funcs, `NewRule` and `NewChain`.

pkg/mesh,pkg/wireguard: allow DNS name endpoints
This commit allows DNS names to be used when specifying the endpoint
for a node in the WireGuard mesh. This is useful in many scenarios, in
particular when operating an IoT device whose public IP is dynamic. This
change allows the administrator to use a dynamic DNS name in the node's
endpoint.

One of the side-effects of this change is that the WireGuard port can
now be specified individually for each node in the mesh, if the
administrator wishes to do so.

*Note*: this commit introduces a breaking change; the
`force-external-ip` node annotation has been removed; its functionality
has been ported over to the `force-endpoint` annotation. This annotation
is documented in the annotations.md file. The expected content of this
annotation is no longer a CIDR but rather a host:port. The host can be
either a DNS name or an IP.

manifests,pkg/encapsulation: Flannel compatibility
This commit adds basic support to run in compatibility mode with
Flannel. This allows clusters running Flannel as their principal
networking solution to leverage some advances Kilo features. In certain
Flannel setups, the clusters can even leverage muti-cloud. For this, the
cluster needs to either run in a full mesh, or Flannel needs to use the
API server's external IP address.

pkg/{encapsulation,mesh}: abstract encapsulation
This commit abstracts away encapsulation to more easily allow for
different types of encapsulation or compatibility with other networking
solutions.
