Before this commit we added the forward ALLOW rule only for the node's
pod CIDR and not all pod CIDRs of a location. This commit adds the
forward ALLOW rule for packages from (source) and to (destination) all
pod CIDRs of the location if the node is a leader node.

* pkg/mesh/routes.go: add flag for generic ACCEPT in FORWARD chain
Some linux distros or docker will set the default policy in the FORWARD
chain in the filter table to DROP. With the new ip-tables-forward-rules
flag a generic ACCEPT for all packages going from and to the pod subnet
is added to the FORWARD chain.

This commit adds a stage to the GitHub Actions CI workflow to verify
that vendor and go.mod/sum are always up-to-date. If the vendored files
require any changes then CI will fail. This ensures that the repo
remains the source of truth.

* docs: kgctl binary install on Archlinux
I've created a package in Arch User Repository for easily installing `kgctl` on Archlinux via an AUR helper like `yay` or `paru`. This internally fetches the binaries from [the GitHub releases page](https://github.com/squat/kilo/releases)

`cobra` automatically prints and error if `runE` returns an error.
Since we explicitly print the error, we need to silence cobra.

Use a maintained fork of certgen.
The former project is not maintained anymore and will not work for
Kubernteses v1.22 because the admission v1beta1 API was dropped.
Also fix the name of the liste-metrics flag.

This commit adds a sub command `webhook` to Kilo.
It will start a https web server that answeres request from a Kubernetes
API server to validate updates and creations of Kilo peers.
It also updates the "Peer Validation" docs to enable users to
install the web hook server and generate the self signed certificates in
the cluster by only applying a manifest.

When updating Kilo to the latest version of the CustomResourceDefinition
API, the Kilo Peer CRD was incorrectly scoped as a namespaced resource
due to differences in the ergonomics of the tooling.
This commit fixes the scoping of the Peer CRD to be cluster-wide.

Since Kilo now uses the `kilo.squat.ai/discovered-endpoints` annotation
for Peer discovery, Kilo no longer needs to update Peer resources, so we
can remove this permission from the ClusterRole. Note, the RBAC in the
manifests is not used today, but we eventually want to migrate to this.

This commit standardizes how we display a `note` in our docs.
Previously, we used a mix of `_Note_:`, `__Note:__`, `> Note`, and `>
**Note**:` among others. Now, all notes appear as `> **Note**:`.

This commit adds a new test suite to the e2e tests that validates
multi-cluster connectivity in Kilo. This is really just an extension of
the testing of the Peers CRD and related tooling that also exercises the
`--allowed-ips` flag of the `kgctl` tool.

This commit enables the filtering of e2e tests that should be run when
using the Makefile's `e2e` target through the specification of the
`BASH_UNIT_FLAGS` environment variable. The value of this variable will
be passed as arguments to the `bash_unit` command, enabling filtering of
tests.

This commit simplifies the check_adjacency helper to us the curl_pod
helper rather than a re-written version of it. It also simplifies the

This commit allows the kind cluster configuration to be parameterized at
call time. This enables the test suite to build multiple clusters with
different configurations, e.g. different CIDRs, different numbers of
nodes, etc.

This commit modifies the logic of the check_adjacent helper so that
rather than expecting the argument to be n^2+n it expects simply n. This
makes it easier to update the caller when the number of nodes in the
cluster changes.

This commit modifies the e2e shell scripts so that the KUBECONFIG

Currently, each test suite spins up its own kind cluster, which results
in longer e2e test times as each test suite needs to wait for the
cluster to be ready and for images to download. This commit creates two
new virtual test suites that are run before and after the actual e2e
tests and are responsible for creating and destroying a kind cluster
respectively. Any test suite that needs a fresh cluster can still spin
up its own using the `create_cluster` helper in the lib.sh file.
