Bharath Vedartham 5c9b688984 validate_cluster: Create node to instance group mapping to get pod instance group 
In the ValidationError struct, there is a field to identify the instance group to
which the ValidationError is associated with.

For pod related ValidationErrors, it is not straightforward to identify the
instance group to which the pod is associated with.

To acheive this, we create a node to instance group mapping in ValidateNodes.
This node to instance group mapping is used in collectPodFailures to identify the
pod instance group by using the pod's hostIp field.

We don't associate system-cluster-critical pods to instance groups as those pod
failures are cluster wide

Bharath Vedartham 49f2a0e10a validate_cluster: Add InstanceGroup field to ValidationError struct 
The InstanceGroup field in ValidationError struct is an optional field meant
to indicate the InstanceGroup which has reported that failure. This field either
holds a pointer to the instance group which caused the validation error or can be
nil which indicates that we were unable to determine the instance group to which
this failure should be attributed to.

This field is mainly used to identify whether a failure is worth waiting for
when validating a particular instance group.

Justin Santa Barbara 31bb16d4d1 Add context.Context to most signatures 
The client-go signature for most methods adds a context.Context
object, and also makes Options mandatory.  Feed through a
context.Context through many of our methods (but use context.TODO to
stop it getting totally out of hand!)

Change code from glog to klog 
We don't call klog.InitFlags yet, because that will cause a flag
redefinition error until we get everyone to stop using glog.  That
will happen when we update to k8s 1.13.

Brad Kim 967f1e86c6 Fix for validating kubeconfig's hosts 
URL's Host field is "host" or "host:port". (see https://golang.org/pkg/net/url/#URL )
"host:port" can't be used as net.LookupHost's parameter.
I recommend using URL.Hostname() instead of URL.Host.

chrislovecnm c7ef856f92 Improving UX for kops validate cluster 
Before the `kops validate cluster` attempts to connect to the K8s API
endpoint, the code now checks to see if the API DNS Entry is the kops
placeholder IP Address 203.0.113.123.  It prints a message to the user
and err's.  There is a new init func in validate cluster that disables
CGO based DNS for Darwin OS.  Darwin does two things with kops
validates; it caches the IP address, and it does not return the
placeholder IP address.  We cannot use CGO base DNS with kops validate.
