cmd/k8s-operator,cmd/containerboot,ipn,k8s-operator: turn off stateful filter for egress proxies. (#12075)
Turn off stateful filtering for egress proxies to allow cluster
traffic to be forwarded to tailnet.

Allow configuring stateful filter via tailscaled config file.

Deprecate EXPERIMENTAL_TS_CONFIGFILE_PATH env var and introduce a new
TS_EXPERIMENTAL_VERSIONED_CONFIG env var that can be used to provide
containerboot a directory that should contain one or more
tailscaled config files named cap-<tailscaled-cap-version>.hujson.
Containerboot will pick the one with the newest capability version
that is not newer than its current capability version.

Proxies with this change will not work with older Tailscale
Kubernetes operator versions - users must ensure that
the deployed operator is at the same version or newer (up to
4 version skew) than the proxies.

Brad Fitzpatrick e968b0ecd7 cmd/tailscale,controlclient,ipnlocal: fix 'up', deflake tests more
The CLI's "up" is kinda chaotic and LocalBackend.Start is kinda
chaotic and they both need to be redone/deleted (respectively), but
this fixes some buggy behavior meanwhile. We were previously calling
StartLoginInteractive (to start the controlclient's RegisterRequest)
redundantly in some cases, causing test flakes depending on timing and
up's weird state machine.

We only need to call StartLoginInteractive in the client if Start itself
doesn't. But Start doesn't tell us that. So cheat a bit and a put the
information about whether there's a current NodeKey in the ipn.Status.
It used to be accessible over LocalAPI via GetPrefs as a private key but
we removed that for security. But a bool is fine.

So then only call StartLoginInteractive if that bool is false and don't
do it in the WatchIPNBus loop.

Nick Khyl caa3d7594f ipn/ipnlocal, net/tsdial: plumb routes into tsdial and use them in UserDial
We'd like to use tsdial.Dialer.UserDial instead of SystemDial for DNS over TCP.
This is primarily necessary to properly dial internal DNS servers accessible
over Tailscale and subnet routes. However, to avoid issues when switching
between Wi-Fi and cellular, we need to ensure that we don't retain connections
to any external addresses on the old interface. Therefore, we need to determine
which dialer to use internally based on the configured routes.

This plumbs routes and localRoutes from router.Config to tsdial.Dialer,
and updates UserDial to use either the peer dialer or the system dialer,
depending on the network address and the configured routes.

Reset dial plan when switching profile (#11933)
When switching profile, the server URL can change (e.g.
because of switching to a self-hosted headscale instance).

If it is not reset here, dial plans returned by old
server (e.g. tailscale control server) will be used to
connect to new server (e.g. self-hosted headscale server),
and the register request will be blocked by it until
timeout, leading to very slow profile switches.

* because a tsdial.Dialer always has a netmon, anything taking both

Brad Fitzpatrick 723c775dbb tsd, ipnlocal, etc: add tsd.System.HealthTracker, start some plumbing
This adds a health.Tracker to tsd.System, accessible via
a new tsd.System.HealthTracker method.

In the future, that new method will return a tsd.System-specific
HealthTracker, so multiple tsnet.Servers in the same process are
isolated. For now, though, it just always returns the temporary
health.Global value. That permits incremental plumbing over a number
of changes. When the second to last health.Global reference is gone,
then the tsd.System.HealthTracker implementation can return a private
Tracker.

The primary plumbing this does is adding it to LocalBackend and its
dozen and change health calls. A few misc other callers are also
plumbed. Subsequent changes will flesh out other parts of the tree
(magicsock, controlclient, etc).

ipn/ipnlocal: reset auto-updates if unsupported on profile load (#11838)
Prior to
1613b18f82 (diff-314ba0d799f70c8998940903efb541e511f352b39a9eeeae8d475c921d66c2ac),
nodes could set AutoUpdate.Apply=true on unsupported platforms via
`EditPrefs`. Specifically, this affects tailnets where default
auto-updates are on.

Fix up those invalid prefs on profile reload, as a migration.

ipn/ipnlocal,ssh/tailssh: reject c2n /update if SSH conns are active (#11820)
Since we already track active SSH connections, it's not hard to
proactively reject updates until those finish. We attempt to do the same
on the control side, but the detection latency for new connections is in
the minutes, which is not fast enough for common short sessions.

Handle a `force=true` query parameter to override this behavior, so that
control can still trigger an update on a server where some long-running
abandoned SSH session is open.

ipn/ipnlocal,clientupdate: disallow auto-updates in containers (#11814)
Containers are typically immutable and should be updated as a whole (and
not individual packages within). Deny enablement of auto-updates in
containers.

Also, add the missing check in EditPrefs in LocalAPI, to catch cases
like tailnet default auto-updates getting enabled for nodes that don't
support it.
