d6c575532a pkg/proxy/healthcheck: rename 'proxier' to 'proxy'
KubeProxy operates with a single health server and two proxies,
one for each IP family. The use of the term 'proxier' in the
types and functions within pkg/proxy/healthcheck can be
misleading, as it may suggest the existence of two health
servers, one for each IP family.

ba57fd7c84 Merge linux and windows kube-proxy metric registration together
Windows proxy metric registration was in a separate file, which had
led to some metrics (eg the new ProxyHealthzTotal and ProxyLivezTotal)
not being registered for Windows even though they were implemented by
platform-generic code.

(A few other metrics were neither registered on, nor implemented on
Windows, and that's probably a bug.)

Also, beyond linux-vs-windows, make it clearer which metrics are
specific to individual backends.

fde1af55d2 Warn users with bad --nodeport-addresses
If users don't pass any --nodeport-addresses, suggest they should pass
`--nodeport-addresses primary`, to avoid accepting NodePort
connections on all interfaces.

If users pass a single-stack --nodeport-addresses in what looks like a
dual-stack cluster, warn them that they probably ought to be passing a
dual-stack --nodeport-addresses.

0b599aa8e3 Add --nodeport-addresses primary
The behavior when you specify no --nodeport-addresses value in a
dual-stack cluster is terrible and we can't fix it, for
backward-compatibility reasons. Actually, the behavior when you
specify no --nodeport-addresses value in a single-stack cluster isn't
exactly awesome either...

Allow specifying `--nodeport-addresses primary` to get the
previously-nftables-backend-specific behavior of listening on only the
node's primary IP or IPs.
