justinsb f2d4eeb104 reconcile: wait for apiserver to response before trying rolling-update 
The rolling-update requires the apiserver (when called without --cloudonly),
so reconcile should wait for apiserver to start responding.

Implement this by reusing "validate cluster", but filtering to only the instance groups
and pods that we expect to be online.

justinsb 859a9fd9f1 chore: refactor factory to accept a cluster 
This should allow us to build our own rest config in future,
rather than relying on the kubeconfig being configured correctly.

To do this, we need to stop sharing the factory between the channels
and kops commands.

justinsb ca67b1ca1e Refactor: rename IsGossip -> UsesLegacyGossip 
We want to be able to use "dns=none" (without peer-to-peer gossip)
even for clusters that have the k8s.local extension.  These were
previously called "gossip clusters", but really that is an
implementation; what actually matters to users is that they don't rely
on writing records into a DNS zone (such as Route53).

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.
