This commit adds the `spec.replicas` field to the `Recorder` custom
resource that allows for a highly available deployment of `tsrecorder`
within a kubernetes cluster.
Many changes were required here as the code hard-coded the assumption
of a single replica. This has required a few loops, similar to what we
do for the `Connector` resource to create auth and state secrets. It
was also required to add a check to remove dangling state and auth
secrets should the recorder be scaled down.

This commit enables user to set service backend to remote destinations, that can be a partial
URL or a full URL. The commit also prevents user to set remote destinations on linux system
when socket mark is not working. For user on any version of mac extension they can't serve a
service either. The socket mark usability is determined by a new local api.

This commit modifies the helm/static manifest configuration for the

do not manually make the change.
This is managed for us when using helm but not when generating the
static manifests.

Adds the ability to rotate discovery keys on running clients, needed for
testing upcoming disco key distribution changes.
Introduces key.DiscoKey, an atomic container for a disco private key,
public key, and the public key's ShortString, replacing the prior
separate atomic fields.
magicsock.Conn has a new RotateDiscoKey method, and access to this is
provided via localapi and a CLI debug command.
Note that this implementation is primarily for testing as it stands, and
regular use should likely introduce an additional mechanism that allows
the old key to be used for some time, to provide a seamless key rotation
rather than one that invalidates all sessions.

This patch changes the behaviour of `tailscale lock log --json` to make
it more useful for users. It also introduces versioning of our JSON output.
## Changes to `tailscale lock log --json`
Previously this command would print the hash and base64-encoded bytes of
each AUM, and users would need their own CBOR decoder to interpret it in
a useful way:
```json
[
{
"Hash": [
80,
136,
151,
…
],
"Change": "checkpoint",
"Raw": "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"
}
]
```
Now we print the AUM in an expanded form that can be easily read by scripts,
although we include the raw bytes for verification and auditing.
```json
{
"SchemaVersion": "1",
"Messages": [
{

This output was previously marked as unstable, and it wasn't very useful,
so changing it should be fine.
## Versioning our JSON output
This patch introduces a way to version our JSON output on the CLI, so we
can make backwards-incompatible changes in future without breaking existing
scripts or integrations.
You can run this command in two ways:
```
tailscale lock log --json
tailscale lock log --json=1
```
Passing an explicit version number allows you to pick a specific JSON schema.
If we ever want to change the schema, we increment the version number and
users must opt-in to the new output.
A bare `--json` flag will always return schema version 1, for compatibility
with existing scripts.

This adds the --proxy-protocol flag to 'tailscale serve' and
'tailscale funnel', which tells the Tailscale client to prepend a PROXY
protocol[1] header when making connections to the proxied-to backend.
I've verified that this works with our existing funnel servers without
additional work, since they pass along source address information via
PeerAPI already.

The feature is currently in private alpha, so requires a tailnet feature
flag. Initially focuses on supporting the operator's own auth, because the
operator is the only device we maintain that uses static long-lived
credentials. All other operator-created devices use single-use auth keys.
Testing steps:
* Create a cluster with an API server accessible over public internet
* kubectl get --raw /.well-known/openid-configuration | jq '.issuer'
* Create a federated OAuth client in the Tailscale admin console with:
* The issuer from the previous step
* Subject claim `system:serviceaccount:tailscale:operator`
* Write scopes services, devices:core, auth_keys
* Tag tag:k8s-operator
* Allow the Tailscale control plane to get the public portion of
the ServiceAccount token signing key without authentication:
* kubectl create clusterrolebinding oidc-discovery \
--clusterrole=system:service-account-issuer-discovery \
--group=system:unauthenticated
* helm install --set oauth.clientId=... --set oauth.audience=...

In #17639 we moved the subscription into NewLogger to ensure we would not race
subscribing with shutdown of the eventbus client. Doing so fixed that problem,
but exposed another: As we were only servicing events occasionally when waiting
for the network to come up, we could leave the eventbus to stall in cases where
a number of network deltas arrived later and weren't processed.
To address that, let's separate the concerns: As before, we'll Subscribe early
to avoid conflicts with shutdown; but instead of using the subscriber directly
to determine readiness, we'll keep track of the last-known network state in a
selectable condition that the subscriber updates for us. When we want to wait,
we'll wait on that condition (or until our context ends), ensuring all the
events get processed in a timely manner.

The connstats package was an unnecessary layer of indirection.
It was seperated out of wgengine/netlog so that net/tstun and
wgengine/magicsock wouldn't need a depenedency on the concrete
implementation of network flow logging.
Instead, we simply register a callback for counting connections.
This PR does the bare minimum work to prepare tstun and magicsock
to only care about that callback.
A future PR will delete connstats and merge it into netlog.
