We were previously relying on unintended behaviour by runc where
all containers where by default given read/write/mknod permissions
for tun devices.
This behaviour was removed in https://github.com/opencontainers/runc/pull/3468
and released in runc 1.2.
Containerd container runtime, used by Docker and majority of Kubernetes distributions
bumped runc to 1.2 in 1.7.24 https://github.com/containerd/containerd/releases/tag/v1.7.24
thus breaking our reference tun mode Tailscale Kubernetes manifests and Kubernetes
operator proxies.
This PR changes the all Kubernetes container configs that run Tailscale in tun mode
to privileged. This should not be a breaking change because all these containers would
run in a Pod that already has a privileged init container.

This is a follow-up to #14112 where our internal kube client was updated
to allow it to emit Events - this updates our sample kube manifests
and tsrecorder manifest templates so they can benefit from this functionality.

Update docs for static Tailscale deployments on kube
to always use firewall mode autodection when in non-userspace.
Also add a note about running multiple replicas and a few suggestions how folks could do that.

This updates all source files to use a new standard header for copyright
and license declaration. Notably, copyright no longer includes a date,
and we now use the standard SPDX-License-Identifier header.
This commit was done almost entirely mechanically with perl, and then
some minimal manual fixes.
