Control can now send down a set of routes along with the domains, and
the routes will be advertised, with any newly overlapped routes being

* cmd/k8s-operator/deploy: deploy a Tailscale IngressClass resource.
Some Ingress validating webhooks reject Ingresses with
.spec.ingressClassName for which there is no matching IngressClass.
Additionally, validate that the expected IngressClass is present,
when parsing a tailscale `Ingress`.
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.

This is in response to logs from a customer that show that we're unable

router: firewall: error adding Tailscale-Process rule: exec: "netsh": cannot run executable found relative to current directory:
There's approximately no reason to ever dynamically look up the path of
a system utility like netsh.exe, so instead let's first look for it
in the System32 directory and only if that fails fall back to the
previous behaviour.
