This commit implements probing of UDP path lifetime on the tail end of
an active direct connection. Probing configuration has two parts -
Cliffs, which are various timeout cliffs of interest, and
CycleCanStartEvery, which limits how often a probing cycle can start,
per-endpoint. Initially a statically defined default configuration will
be used. The default configuration has cliffs of 10s, 30s, and 60s,
with a CycleCanStartEvery of 24h. Probing results are communicated via
clientmetric counters. Probing is off by default, and can be enabled
via control knob. Probing is purely informational and does not yet
drive any magicsock behaviors.

are preserved.

This change allows us to perform batch modification for new route
advertisements and route removals. Additionally, we now handle the case
where newly added routes are covered by existing ranges.
This change also introduces a new appctest package that contains some
shared functions used for testing.

The new 'toolchain' directive in go.mod can sometimes force
the use of an upstream toolchain against our wishes. Concurrently,
some of our dependencies have added the 'toolchain' directive, which
transitively adds it to our own go.mod. Force all uses of gocross to
ignore that directive and stick to our customized toolchain.

* cmd/k8s-operator/deploy: deploy a Tailscale IngressClass resource.
Some Ingress validating webhooks reject Ingresses with

Additionally, validate that the expected IngressClass is present,

We currently do not utilize the IngressClass,
however we might in the future at which point
we might start requiring that the right class
for this controller instance actually exists.

The lack of type-safety in context.WithValue leads to the common pattern
of defining of package-scoped type to ensure global uniqueness:
type fooKey struct{}
func withFoo(ctx context, v Foo) context.Context {
return context.WithValue(ctx, fooKey{}, v)
}
func fooValue(ctx context) Foo {
v, _ := ctx.Value(fooKey{}).(Foo)
return v
}
where usage becomes:
ctx = withFoo(ctx, foo)
foo := fooValue(ctx)
With many different context keys, this can be quite tedious.
Using generics, we can simplify this as:
var fooKey = ctxkey.New("mypkg.fooKey", Foo{})
where usage becomes:
ctx = fooKey.WithValue(ctx, foo)
foo := fooKey.Value(ctx)

When establishing connections to the ipnserver, we validate that the
local user is allowed to connect. If Tailscale is currently being
managed by a different user (primarily for multi-user Windows installs),
we don't allow the connection.
With the new device web UI, the inbound connection is coming from
tailscaled itself, which is often running as "NT AUTHORITY\SYSTEM".
In this case, we still want to allow the connection, even though it
doesn't match the user running the Tailscale GUI. The SYSTEM user has
full access to everything on the system anyway, so this doesn't escalate
privileges.
Eventually, we want the device web UI to run outside of the tailscaled
process, at which point this exception would probably not be needed.

The manage client always listens on http (non-secure) port 5252. If the
login client is loaded over https, then the connectivity check to `/ok`
will fail with a mixed-content error. Mixed-content enforcement is a
browser setting that we have no control over, so there's no way around
this.
In this case of the login client being loaded over https, we skip the
connectivity check entirely. We will always render the sign-in button,
though we don't know for sure if the user has connectivity, so we
provide some additional help text in case they have trouble signing in.

cmd/k8s-operator: fix base truncating for extra long Service names
StatefulSet names for ingress/egress proxies are calculated
using Kubernetes name generator and the parent resource name
as a base.
The name generator also cuts the base, but has a higher max cap.
This commit fixes a bug where, if we get a shortened base back
from the generator, we cut off too little as the base that we
have cut will be passed into the generator again, which will
then itself cut less because the base is shorter- so we end up
with a too long name again.
