Windows containers do not include a route to the GCE metadata server by
default. This check is causing the "DNS should provide DNS for the
cluster" test to fail for clusters with Windows nodes
(https://testgrid.k8s.io/sig-windows#gce-windows-master&width=20).
Tested that this works by running "DNS should provide DNS for the
cluster" against an e2e cluster with Windows nodes brought up on GCE.
- Pass most of the flags via kube-env, similar to Kubelet, to make it
easier to reconfigure.
- Use kube-proxy's kubeconfig file to pass the API server address,
rather than the --master flag.
- Make KUBEPROXY_ARGS a required variable in Windows kube-env, similar
to KUBELET_ARGS.
Current IPv6 e2e test for external connectivity is using a
domain address (google.com) as target.
However, the same IPv4 test uses the well known Google DNS address
8.8.8.8.
We should be coherent in the testing, this patch changes the target to use
the Google IPv6 DNS address 2001:4860:4860::8888.
Minor optimization in the code that attempts to assign whole
sockets/cores in case the number of CPUs requested is higher
than CPUs-per-socket/core: check if the number of requested
CPUs is higher than CPUs-per-socket/core before retrieving
and iterating the free sockets/cores, and break the loops
when that is no longer the case.

Currently OpenStack cloud provider reads user credentials from config
file, where data is stored in clear text. This approach is not recommended,
as it is a serious security issue.
This commit add an ability to read the config from secrets, if necessary.
To do so, two new parameters are added to the config: SecretNamespace and
SecretName. If they are specified, the provider will try to read config
from the secret.
It looks like node does become unschedulable for the pod
but condition does not get added to the pod in time.
Also ginkgo could retry the test and hence it helps to use
unique node label for scheduling.
An example of incorrect log message:
{
"component":"virtctl",
"level":"info",
"msg":"Config loaded from fileocp/auth/kubeconfig",
"pos":"loader.go:359",
"timestamp":"2019-03-07T18:50:20.923470Z"
}
Note how the resulting message has no characters between the text and
file name.
