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.

pkg/mesh: ignore CNI IP from private IPs
We need to ignore the CNI IP address from the searched IPs, as this will
not be a routable IP address.

pkg/mesh: edge case external = internal
Add an exception to the route generation rules for when the external IP
of a node equals the internal IP. In this case, we cannot route traffic
through a tunnel.

manifests: keep private key between restarts
This commit ensures that the WireGuard private key is re-used between
container restarts. The result of this is that external peers can keep
using their configuration and don't need to be re-configured just
because the Kilo container restarted.

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.

pkg/mesh,cmd: add WireGuard IP to Nodes
This allows admins or users to have some easy visibility into the
configuration of the Kilo cluster.

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.

pkg/mesh: rename mesh granularity types
This commit renames the mesh granularity types to make them more
intuitive. The functionality provided by them remains exactly the same.

*: add complete CNI support
This commit enables Kilo to work as an independent networking provider.
This is done by leveraging CNI. Kilo brings the necessary CNI plugins to
operate and takes care of all networking.

Add-on compatibility for Calico, Flannel, etc, will be re-introduced
shortly.

*: add peer VPN support
This commit adds support for defining arbitrary peers that should have
access to the VPN. In k8s, this is accomplished using the new Peer CRD.

pkg/mesh: metric for reconcile attempts
This commit exposes a new Prometheus to track the number of
reconciliation attempts. This is important, as without this, the number
of errors it not too helpful. A more valuable statistic is the
proportion of reconciliations that result in an error.

pkg/{k8s,mesh}: introduce liveness checks
This commit introduces liveness checks to Kilo. This allows the Kilo
daemons to take nodes with inactive or dead Kilo deamons out of the
topology until they are alive again.
