Kubernetes can generate StatefulSet names that are too long and result in invalid Pod revision hash label values.
Calculate whether a StatefulSet name generated for a Service or Ingress
will be too long and if so, truncate it.

Marshal as a JSON list instead of a map. Because set elements are
`comparable` and not `cmp.Ordered`, we cannot easily sort the items
before marshaling.

It's possible to do this with a combination of watch-ipn and jq, but looking
at the netmap while debugging is quite common, so it's nice to have a one-shot
command to get it.

jq doens't like non-json output in the json stream, and works more happily
when the input stream EOFs at some point. Move non-json words to stderr, and
add a parameter to stop watching and exit after some number of objects.

Config.singleResolverSet returns true if all routes have the same resolvers,
even if the routes have no resolvers. If none of the routes have a specific
resolver, the default should be used instead. Therefore, check for more than
0 instead of nil.

This PR starts to persist the NetMap tailnet name in SetPrefs so that tailscaled
clients can use this value to disambiguate fast user switching from one tailnet
to another that are under the same exact login. We will also try to backfill
this information during backend starts and profile switches so that users don't
have to re-authenticate their profile. The first client to use this new
information is the CLI in 'tailscale switch -list' which now uses text/tabwriter
to display the ID, Tailnet, and Account. Since account names are ambiguous, we
allow the user to pass 'tailscale switch ID' to specify the exact tailnet they
want to switch to.

This creates a new /api/up endpoint which is exposed in the login
client, and is solely focused on logging in. Login has been removed from
the nodeUpdate endpoint.
This also adds support in the LoginClientView for a stopped node that
just needs to reconnect, but not necessarily reauthenticate. This
follows the same pattern in `tailscale up` of just setting the
WantRunning user pref.

This takes advantage of existing functionality in ipn/ipnlocal to adjust
the local clock based on periodic time signals from the control server.
This way, when checking things like SSHRule expirations, calculations are
protected incorrectly set local clocks.

This change removes the existing debug-web-client localapi endpoint
and replaces it with functions passed directly to the web.ServerOpts
when constructing a web.ManageServerMode client.
The debug-web-client endpoint previously handled making noise
requests to the control server via the /machine/webclient/ endpoints.
The noise requests must be made from tailscaled, which has the noise
connection open. But, now that the full client is served from
tailscaled, we no longer need to proxy this request over the localapi.

When the viewing user is accessing a webclient not over Tailscale,
they must connect over Tailscale before being able to log into the
full management client, which is served over TS. This change adds
a check that the user is able to access the node's tailscale IP.
If not able to, the signin button is disabled. We'll also be adding
Copy here to help explain to the user that they must connect to
Tailscale before proceeding.

This `go get` action has been running very slowly, and I'm pretty sure
it's because we're building gocross on the first `./tool/go` run, and
because we've set `GOPROXY=direct`, it's going directly to GitHub to
fetch all of the gocross dependencies.

I don't believe this has ever worked, since we didn't allow POST
requests in the login client. But previously, we were primarily using
the legacy client, so it didn't really matter. Now that we've removed
the legacy client, we have no way to login.
This fixes the login client, allowing it to login, but it still needs to
be refactored to expose a dedicated login method, without exposing all
the node update functionality.

Adds a new sync.Mutex field to the webClient struct, rather than
using the general LocalBackend mutex. Since webClientGetOrInit
(previously WebClientInit) gets called on every connection, we
want to avoid holding the lock on LocalBackend just to check if

Moves all web_client.go funcs over to using the webClient.mu field.
