1.50.0 switched containerboot from using `tailscale up`
to `tailscale login`. A side-effect is that a re-usable
authkey is now re-applied on every boot by `tailscale login`,
where `tailscale up` would ignore an authkey if already
authenticated.
Though this looks like it is changing the default, in reality
it is setting the default to match what 1.48 and all
prior releases actually implemented.

The test was sending SIGKILL to containerboot, which results in no
signal propagation down to the bash script that is running as a child
process, thus it leaks.
Minor changes to the test daemon script, so that it cleans up the socket
that it creates on exit, and spawns fewer processes.

In typical k8s setups, the MTU configured on the eth0 interfaces is typically 1500 which
results in packets being dropped when they make it to proxy pods as the tailscale0 interface
has a 1280 MTU.
As the primary use of this functionality is TCP, add iptables based MSS clamping to allow
connectivity.

We had two implemenetations of the kube client, merge them.
containerboot was also using a raw http.Transport, this also has
the side effect of making it use a http.Client

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.

We still accept the previous TS_AUTH_KEY for backwards compatibility, but the documented option name is the spelling we use everywhere else.

In some configurations, user explicitly do not want to store
tailscale state in k8s secrets, because doing that leads to
some annoying permission issues with sidecar containers.
With this change, TS_KUBE_SECRET="" and TS_STATE_DIR=/foo
will force storage to file when running in kubernetes.
Fixes#6704.

We still have to shell out to `tailscale up` because the container image's
API includes "arbitrary flags to tailscale up", unfortunately. But this
should still speed up startup a little, and also enables k8s-bound containers
to update their device information as new netmap updates come in.
