This is mostly for containerboot instances that are Kubernetes Operator proxies
to make it possible for the operator to discover the actual Tailscale
version of the proxy.

This is a follow-up to #14112 where our internal kube client was updated
to allow it to emit Events - this updates our sample kube manifests
and tsrecorder manifest templates so they can benefit from this functionality.

Adds functionality to kube client to emit Events.
Updates kube store to emit Events when tailscaled state has been loaded, updated or if any errors where
encountered during those operations.
This should help in cases where an error related to state loading/updating caused the Pod to crash in a loop-
unlike logs of the originally failed container instance, Events associated with the Pod will still be
accessible even after N restarts.

I merged 5cae7c51bf (removing Notify.BackendLogID) and 93db503565
(adding another reference to Notify.BackendLogID) that didn't have merge
conflicts, but didn't compile together.
This removes the new reference, fixing the build.

Limit spamming GUIs with boring updates to once in 3 seconds, unless
the notification is relatively interesting and the GUI should update
immediately.
This is basically @barnstar's #14119 but with the logic moved to be
per-watch-session (since the bit is per session), rather than
globally. And this distinguishes notable Notify messages (such as
state changes) and makes them send immediately.

The v2 endpoint supports HTTP/2 bidirectional streaming and acks for
received bytes. This is used to detect when a recorder disappears to
more quickly terminate the session.

Back in the day this testcontrol package only spoke the
nacl-boxed-based control protocol, which used this.
Then we added ts2021, which didn't, but still sometimes used it.
Then we removed the old mode and didn't remove this parameter
in 2409661a0d.

Previously we required the program to be running in a test or have
TS_CONTROL_IS_PLAINTEXT_HTTP before we disabled its https fallback
on "http" schema control URLs to localhost with ports.
But nobody accidentally does all three of "http", explicit port
number, localhost and doesn't mean it. And when they mean it, they're
testing a localhost dev control server (like I was) and don't want 443
getting involved.
As of the changes for #13597, this became more annoying in that we
were trying to use a port which wasn't even available.

We currently annotate pods with a hash of the tailscaled config so that
we can trigger pod restarts whenever it changes. However, the hash
updates more frequently than is necessary causing more restarts than is
necessary. This commit removes two causes; scaling up/down and removing
the auth key after pods have initially authed to control. However, note
that pods will still restart on scale-up/down because of the updated set
of volumes mounted into each pod. Hopefully we can fix that in a planned
follow-up PR.

Otherwise all the clients only using control/controlhttp for the
ts2021 HTTP client were also pulling in WebSocket libraries, as the
server side always needs to speak websockets, but only GOOS=js clients
speak it.
This doesn't yet totally remove the websocket dependency on Linux because
Linux has a envknob opt-in to act like GOOS=js for manual testing and force
the use of WebSockets for DERP only (not control). We can put that behind
a build tag in a future change to eliminate the dep on all GOOSes.

Adds a /disconnect-control local API endpoint that just shuts down control client.
This can be run before shutting down an HA subnet router/app connector replica - it will ensure
that all connection to control are dropped and control thus considers this node inactive and tells
peers to switch over to another replica. Meanwhile the existing connections keep working (assuming
that the replica is given some graceful shutdown period).

This adds a new generic result type (motivated by golang/go#70084) to
try it out, and uses it in the new lineutil package (replacing the old
lineread package), changing that package to return iterators:
sometimes over []byte (when the input is all in memory), but sometimes
iterators over results of []byte, if errors might happen at runtime.
