add mutex for kubenet
I saw a bunch of weird cases in kubenet suite. For instance, SetUpPod return successfully, but right after that, kubelet cannot retrieve podIP from podCIDR map.

Run Kubemark builds inside Docker
Since Docker-in-Docker is tricky to get right (esp. wrt volume mounts), I'm only enabling it when necessary for a build (e.g. for kubemark).

Correct the display of the output when e.g. starting the kubelet fails in the node e2e tests. This
change makes it display a string instead of an array of decimal values.

Unify termination signal handling across platforms
The signals are used to ensure proper execution of cleaning up actions to restore a terminal in:
- [pkg/kubectl/cmd/attach.go#L163-L226](b8d000853e/pkg/kubectl/cmd/attach.go (L163-L226))
- [pkg/kubectl/cmd/util/editor/editor.go#L112-L137](b8d000853e/pkg/kubectl/cmd/util/editor/editor.go (L112-L137))
All supported platforms can handle the same set of signals we're interested in, thus we don't need build contraints to use a set of signals on Linux, while restricting ourselves to only SIGINT on Darwin and Windows.
According to the documentation of os/signal, similar to SIGINT and SIGTERM, SIGHUP causes the program to exit, therefore add it to the list of handled signals.
The fist commit is part of #23643.

Framework support for node e2e.
This should let us port existing e2e tests to the node e2e suite, if the tests are node specific.
