kube,tailcfg: store parsed recorder tags in a separate field (#12429)
Add an additional RecorderAddrs field to tailscale.com/cap/kubernetes
capability. RecorderAddrs will only be populated by control
with the addresses of any tsrecorder tags set via Recorder.

tailcfg,cmd/k8s-operator,kube: move Kubernetes cap to a location that can be shared with control (#12236)
This PR is in prep of adding logic to control to be able to parse
tailscale.com/cap/kubernetes grants in control:
- moves the type definition of PeerCapabilityKubernetes cap to a location
shared with control.
- update the Kubernetes cap rule definition with fields for granting
kubectl exec session recording capabilities.
- adds a convenience function to produce tailcfg.RawMessage from an
arbitrary cap rule and a test for it.

An example grant defined via ACLs:
"grants": [{
      "src": ["tag:eng"],
      "dst": ["tag:k8s-operator"],
      "app": {
        "tailscale.com/cap/kubernetes": [{
            "recorder": ["tag:my-recorder"]
	    “enforceRecorder”: true
        }],
      },
    }
]
This grant enforces `kubectl exec` sessions from tailnet clients,
matching `tag:eng` via API server proxy matching `tag:k8s-operator`
to be recorded and recording to be sent to a tsrecorder instance,
matching `tag:my-recorder`.

The type needs to be shared with control because we want
control to parse this cap and resolve tags to peer IPs.

Maisem Ali af97e7a793 tailcfg,all: add/plumb Node.IsJailed
This adds a new bool that can be sent down from control
to do jailing on the client side. Previously this would
only be done from control by modifying the packet filter
we sent down to clients. This would result in a lot of
additional work/CPU on control, we could instead just
do this on the client. This has always been a TODO which
we keep putting off, might as well do it now.

Percy Wegmann 50fb8b9123 tailfs: replace webdavfs with reverse proxies
Instead of modeling remote WebDAV servers as actual
webdav.FS instances, we now just proxy traffic to them.
This not only simplifies the code, but it also allows
WebDAV locking to work correctly by making sure locks are
handled by the servers that need to (i.e. the ones actually
serving the files).

Maisem Ali 19a9d9037f tailcfg: add NodeCapMap
Like PeerCapMap, add a field to `tailcfg.Node` which provides
a map of Capability to raw JSON messages which are deferred to be
parsed later by the application code which cares about the specific
capabilities. This effectively allows us to prototype new behavior
without having to commit to a schema in tailcfg, and it also opens up
the possibilities to develop custom behavior in tsnet applications w/o
having to plumb through application specific data in the MapResponse.

Brad Fitzpatrick ba5aa2c486 version, cmd/tailscale: add version.Meta, tailscale version --json
Add `tailscale version --json` JSON output mode. This will be used
later for a double-opt-in (per node consent like Tailscale SSH +
control config) to let admins do remote upgrades via `tailscale
update` via a c2n call, which would then need to verify the
cmd/tailscale found on disk for running tailscale update corresponds
to the running tailscaled, refusing if anything looks amiss.

Plus JSON output modes are just nice to have, rather than parsing
unstable/fragile/obscure text formats.

Brad Fitzpatrick 45a3de14a6 cmd/tailscaled, tailcfg, hostinfo: add flag to disable logging + support
As noted in #5617, our documented method of blocking log.tailscale.io
DNS no longer works due to bootstrap DNS.

Instead, provide an explicit flag (--no-logs-no-support) and/or env
variable (TS_NO_LOGS_NO_SUPPORT=true) to explicitly disable logcatcher
uploads. It also sets a bit on Hostinfo to say that the node is in that
mode so we can end any support tickets from such nodes more quickly.

This does not yet provide an easy mechanism for users on some
platforms (such as Windows, macOS, Synology) to set flags/env. On
Linux you'd used /etc/default/tailscaled typically. Making it easier
to set flags for other platforms is tracked in #5114.

Fixes #5617
