This commit will add a new control i.e. Describe
which will describe a k8s resource similar to kubectl describe.

Upgraded from 99c19923, branch release-3.0.
This required fetching or upgrading the following:
* k8s.io/api to kubernetes-1.9.1
* k8s.io/apimachinery to kubernetes-1.9.1
* github.com/juju/ratelimit to 1.0.1
* github.com/spf13/pflag to 4c012f6d
Also, update Scope's imports/function calls to be compatible with the new client.
Spec.Replicas is a *int32, with a value of nil occurring when the user doesn't set it.
In this case k8s defaults to 1, so we mimic this to show the effective value.
This namely involved importing new libraries and using the new Clientset.
Changes worth mentioning:
* The new kubernetes library doesn't provide StoreToLister wrappers, so now I am going the casting directly.
* Deleting the pods and getting their logs is done in a cleaner way (using the
Clientset instead of the lower-level RESTclient).
Since there are multiple types in the same topology, displaying the type is important.
We do this in multiple places:
* Add node type to minor label
* Add node type as metadata and include in metadata template.
Even though this will always be the same for every node of that topology, this was
the easiest way to add it so it displays in the table view.
Note we can't control ordering of columns in table view, it's always alphabetical.
This allows plugins to add controls to nodes that already have some
controls set by other plugin. Previously only the last plugin that
sets the controls in the node would have its controls visible. That
was because of NodeControls' Merge function that actually weren't
merging data from two inputs, but rather returning data that was newer
and discarding the older one.
