Let's wait for the local node (aka the kubelet)
to be ready before to query podresources again,
to avoid false negatives.

If you pass just an IP address to "-s" or "-d", the iptables command
will fill in the correct mask automatically.
Originally, the proxier was just hardcoding "/32" for all of these,
which was unnecessary but simple. But when IPv6 support was added, the
code was made more complicated to deal with the fact that the "/32"
needed to be "/128" in the IPv6 case, so it would parse the IPs to
figure out which family they were, which in turn involved adding some
checks in case the parsing fails (even though that "can't happen" and
the old code didn't check for invalid IPs, even though that would
break the iptables-restore if there had been any).
Anyway, all of that is unnecessary because we can just pass the IP
strings to iptables directly rather than parsing and unparsing them
first.
(The diff to proxier_test.go is just deleting "/32" everywhere.)
If GetNodeAddresses() fails (eg, because you passed the wrong CIDR to
`--nodeport-addresses`), then any NodePort services would end up with
only half a set of iptables rules. Fix it to just not output the
NodePort-specific parts in that case (in addition to logging an error
about the GetNodeAddresses() failure).
The iptables and ipvs proxiers both had a check that none of the
elements of svcInfo.LoadBalancerIPStrings() were "", but that was
already guaranteed by the svcInfo code. Drop the unnecessary checks
and remove a level of indentation.
DKC is being removed and we don't want it to continue flaking the rest
of our tests. Lets disable them when dkc is disabled rather than hard
failing. This fits more in line with our other E2Es, and reduces the
maintenance load in test-infra.
we need to make sure the system state is completely cleaned up
again, to avoid to mess up with the shared node state, before
we transition from one test to another.

Since commit 42dd01aa3f the cpuRequest is in millicores, hence
we need to properly check translating to exclusive cpus
when verifying the resource allocation.

the intent is to make the code more readable, no intended
changes in behaviour. Now it should be a bit more explicit
why the code is checking some values.

Once kubernetes#104613 and kubernetes#104693
merge, we'll have OS field in pod spec. Kubelet should start rejecting pods
where pod.Spec.OS and node's OS(using runtime.GOOS) won't match
* Fix regression in kube-proxy
Don't use a prepend() - that allocates. Instead, make Write() take
either strings or slices (I wish we could express that better).
* WIP: switch to intf
* WIP: less appends
* tests and ipvs
