James Tucker 9eaa56df93 tsweb: update doc on BucketedStatsOptions.Finish to match behavior
I originally came to update this to match the documented behavior, but
the code is deliberately avoiding this behavior currently, making it
hard to decide how to update this. For now just align the documentation
to the behavior.

safeweb: move http.Serve for HTTP redirects into lib (#11592)
Refactor the interaction between caller/library when establishing the
HTTP to HTTPS redirects by moving the call to http.Serve into safeweb.
This makes linting for other uses of http.Serve easier without having to
account for false positives created by the old interface.

logtail: always zstd compress with FastestCompression and LowMemory (#11583)
This is based on empirical testing using actual logs data.

FastestCompression only incurs a marginal <1% compression ratio hit
for a 2.25x reduction in memory use for small payloads
(which are common if log uploads happen at a decently high frequency).
The memory savings for large payloads is much lower
(less than 1.1x reduction).

LowMemory only incurs a marginal <5% hit on performance
for a 1.6-2.0x reduction in memory use for small or large payloads.

The memory gains for both settings justifies the loss of benefits,
which are arguably minimal.

cmd/{k8s-nameserver,k8s-operator},k8s-operator: add a kube nameserver, make operator deploy it (#11017)
* cmd/k8s-nameserver,k8s-operator: add a nameserver that can resolve ts.net DNS names in cluster.

Adds a simple nameserver that can respond to A record queries for ts.net DNS names.
It can respond to queries from in-memory records, populated from a ConfigMap
mounted at /config. It dynamically updates its records as the ConfigMap
contents changes.
It will respond with NXDOMAIN to queries for any other record types
(AAAA to be implemented in the future).
It can respond to queries over UDP or TCP. It runs a miekg/dns
DNS server with a single registered handler for ts.net domain names.
Queries for other domain names will be refused.

The intended use of this is:
1) to allow non-tailnet cluster workloads to talk to HTTPS tailnet
services exposed via Tailscale operator egress over HTTPS
2) to allow non-tailnet cluster workloads to talk to workloads in
the same cluster that have been exposed to tailnet over their
MagicDNS names but on their cluster IPs.

safeweb: init (#11467)
Updates https://github.com/tailscale/corp/issues/8027

Safeweb is a wrapper around http.Server & tsnet that encodes some
application security defaults.

Safeweb asks developers to split their HTTP routes into two
http.ServeMuxs for serving browser and API-facing endpoints
repsectively. It then wraps these HTTP routes with the
context-appropriate security controls.

safeweb.Server#Serve will serve the HTTP muxes over the provided
listener. Caller are responsible for creating and tearing down their
application's listeners. Applications being served over HTTPS that wish
to implement HTTP redirects can use the Server#HTTPRedirect handler to
do so.

Brad Fitzpatrick 7b34154df2 all: deprecate Node.Capabilities (more), remove PeerChange.Capabilities [capver 89]
First we had Capabilities []string. Then
https://tailscale.com/blog/acl-grants (#4217) brought CapMap, a
superset of Capabilities. Except we never really finished the
transition inside the codebase to go all-in on CapMap. This does so.

Notably, this coverts Capabilities on the wire early to CapMap
internally so the code can only deal in CapMap, even against an old
control server.

In the process, this removes PeerChange.Capabilities support, which no
known control plane sent anyway. They can and should use
PeerChange.CapMap instead.
