The Kubernetes API server proxy is getting the ability to serve on a
Tailscale Service instead of individual node names. Update the configure
kubeconfig sub-command to accept arguments that look like a Tailscale
Service. Note, we can't know for sure whether a peer is advertising a
Tailscale Service, we can only guess based on the ExtraRecords in the
netmap and that IP showing up in a peer's AllowedIPs.
Also adds an --http flag to allow targeting individual proxies that can
be adverting on http for their node name, and makes the command a bit
more forgiving on the range of inputs it accepts and how eager it is to
print the help text when the input is obviously wrong.

Also capitalises the start of all ShortHelp, allows subcommands to be hidden
with a "HIDDEN: " prefix in their ShortHelp, and adds a TS_DUMP_HELP envknob
to look at all --help messages together.

cmd/tailscale/cli: respect $KUBECONFIG
* `$KUBECONFIG` is a `$PATH`-like: it defines a *list*.
`tailscale config kubeconfig` works like the rest of the
ecosystem so that if $KUBECONFIG is set it will write to the first existant file in the list, if none exist then
the final entry in the list.
* if `$KUBECONFIG` is an empty string, the old logic takes over.
Notes:
* The logic for file detection is inlined based on what `kind` does.
Technically it's a race condition, since the file could be removed/added
in between the processing steps, but the fallout shouldn't be too bad.
https://github.com/kubernetes-sigs/kind/blob/v0.23.0-alpha/pkg/cluster/internal/kubeconfig/internal/kubeconfig/paths.go
* The sandboxed (App Store) variant relies on a specific temporary
entitlement to access the ~/.kube/config file.
The entitlement is only granted to specific files, and so is not
applicable to paths supplied by the user at runtime.
While there may be other ways to achieve this access to arbitrary
kubeconfig files, it's out of scope for now.

When a user deletes the last cluster/user/context from their
kubeconfig via 'kubectl delete-[cluster|user|context] command,
kubectx sets the relevant field in kubeconfig to 'null'.
This was breaking our conversion logic that was assuming that the field
is either non-existant or is an array.
