Cleanup k8s script noise with a verbosity concept
Fixes https://github.com/kubernetes/kubernetes/issues/30109
The KUBE_VERBOSE environment variable sets the verbosity level to
use. Log messages can specify a verbosity by setting the V
variable. e.g.
V=2 kube::log::info foo bar
Would only print "foo bar" if $KUBE_VERBOSE >= 2.
Examples:
Default verbosity (1 for make commands):
```
$ make kubelet
