because of the way the iptables rules are reconciled, having the encapsulation
rules at the end of the slice of rules results in them being deleted and re-added
many times, even though they are very static. Prepending them to the slice of
rules prevents this from happening, making that iptables chain more stable
and saving a bunch of roundtrips to iptables.
The e2e tests are not flaky anymore, so we should run them daily to see
if they break for whatever reason. This way we notice before someone
makes a "goog" PR.

* Pin boringtun image tag
Pin the image to a tag before boringtun's cli changed.
Specifically the --disable-drop-privileges flag need a boolean param.
* Fix image name
* feat: cilium add-mode support
when cni management by kilo is disable, we can use existing cluster's cni setup thanks to add-on mode
https://kilo.squat.ai/docs/introduction#add-on-mode
* feat: manifest example for cilium addon mode
* fix: apply comment from PR review
* fix: add mutex to interface retrieval into flannel addon mode
* CI: use staticcheck for linting
This commit switches the linter for Go code from golint to staticcheck.
Golint has been deprecated since last year and staticcheck is a
recommended replacement.

This commit enhances the Kilo agent internal HTTP server to include
pprof endpoints. For simplicity, this commit migrates the internal
server creation to https://github.com/metalmatze/signal/internalserver,
which allows for easy registration of common internal server
observability endpoints.

- bump golang 1.17 -> 1.18
- bump alpine 3.14 -> 3.15
- revendor
We need to use golang instead of golang:alpine because it does not
contain git anymore. This should be fine as we are not enabling CGO,
thus not linking against musl instead of libc.

Currently, Kilo _only_ supports adding firewall rules via the legacy
iptables API. This means that on systems using nftables in the host
network namespace, the namespace will be polluted and both firewall
infrastructures will be used, causing unexpected and difficult
to predict interactions. In other words, networking may not work as
expected on nftables-based systems.
This PR fixes this by using the iptables-wrappers project [0] to install
run-time detection of the in-use iptables backend.

As mentioned in the Kilo Slack [0], Kubernetes supports CNI 0.4.0 and
does not yet support 1.0.0. Correspondingly, this commit downgrades the
declared CNI version in the configuration to 0.4.0 and crucially updates
the configuration used in the e2e tests to exercise this new CNI
version.

* CNI: bump to 1.0.1
This commit bumps the declared version of CNI in the Kilo manifests to
1.0.1. This is possible with no changes to the configuration lists
because our simple configuration is not affected by any of the
deprecations, and there was effectively no change between 0.4.0 and
1.0.0, other than the declaration of a stable API. Similarly, this
commit also bumps the version of the CNI library and the plugins
package.
Bumping to CNI 1.0.0 will help ensure that Kilo stays compatible with
container runtimes in the future.

Currently,the job to build kgctl binaries is named `linux`, which
suggests to the reader that the job is only building binaries for Linux,
