pkg/mesh/routes.go: add flag for generic ACCEPT in FORWARD chain (#244)
* 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.

a6eef5a8cf .github/workflows: ensure vendor is clean
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

docs: kgctl binary install on Archlinux (#238)
* 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)

cmd/kg/*: sub command peer validation webhook
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.

pkg/k8s: fix resource scope of Kilo CRD
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.

manifests,e2e: reduce cluster role permissions (#211)
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.
