39efba528f cmd/containerboot: use TS_AUTHKEY as the parameter for auth keys
We still accept the previous TS_AUTH_KEY for backwards compatibility, but the documented option name is the spelling we use everywhere else.

Updates #6321

af3127711a cmd/containerboot: allow disabling secret storage in k8s.
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.

1b65630e83 cmd/containerboot: switch to IPN bus monitoring instead of polling.
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.

Fixes #6657

da8def8e13 all: remove old +build tags
The //go:build syntax was introduced in Go 1.17:

https://go.dev/doc/go1.17#build-lines

gofmt has kept the +build and go:build lines in sync since
then, but enough time has passed. Time to remove them.

Done with:

    perl -i -npe 's,^// \+build.*\n,,' $(git grep -l -F '+build')

76904b82e7 cmd/containerboot: PID1 for running tailscaled in a container.
This implements the same functionality as the former run.sh, but in Go
and with a little better awareness of tailscaled's lifecycle.

Also adds TS_AUTH_ONCE, which fixes the unfortunate behavior run.sh had
where it would unconditionally try to reauth every time if you gave it
an authkey, rather than try to use it only if auth is actually needed.
This makes it a bit nicer to deploy these containers in automation, since
you don't have to run the container once, then go and edit its definition
to remove authkeys.
