This change creates a host topology from cluster-wide probe using
kubernetes nodes with cordon/un-cordon control. This also adds the
logic to merge the controls coming from different probes for host
topology.
Dockershim has added a label `io.kubernetes.docker.type` for at least
four years, where the pause container is of type `podsandbox`. This
should be more reliable than trying to keep up with everyone's name
for the pause container.
This dependency makes it harder to see the structure of the program,
and sometimes complicates compilation.
Mostly just changing the source of strings that are already exported
from the report package. A few new strings have to be moved there,
plus the function `IsPauseImageName()`.
This covers:
- Implementation of the job resource in probe
- Reporter changes for the job
- Add Describe Control to the job
- Pass job object to the kube controller renderer
ToDo:
- Need to decide the shape for the Job.

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

This avoids side-effects from reporting Kubernetes from a
cluster-level probe, and removes a lie from the probe data.
Rather than do the work every time the probe sends a report, we do it
every time the app renders endpoints, which should be once per merged
report set.

- Refactor dotted edge logic.
- Change Storage view to show storage components as well as all
the pods.
- Sentence case storage related variables.

This will:
- Add StorageClass resource. Storage classes are mentioned
in the PVC spec. We're using storage class name from PVC spec to
add adjacency to the PVC node.
- Add square sheet shape for StorageClass.
- Add storage filter in the PODS topology.
Storage Filter will allow user to see distinct view of
stateful applications.
- Add visually distinct edge to show storage adjacency.

This will
- Add Kubernetes volume resources such as PV, PVC.
- Add shapes for Kubernetes PV and PVC
- Add `Cylinder` shape for PV and `Dotted Cylinder` shape for PVC.

* Sentence cased text everywhere
Follows Weave Cloud's direction of sentence case on most things.
* More space between sorter caret and label
* Use full topology name for table header
* Refactor: func has already access to probeID
* Allow controls for more k8s topologies
Controls for nodes generally need to know about the probe that is in
control of them.
This PR appends the probe ID info to k8s topologies CronJob, DaemonSet,
Service, and StatefulSet. Therefore allowing plugins to append controls.
* Remove superfluous error check
* Add some tests to verify controls allowance
This prevents cluttering host.LocalNetworks with lots of /32
addresses. These were unsightly and rather distracting in the UI. They
also bloated the report and slowed down server-side rendering.
Fixes#2748.
Most of the time you only care about cronjobs, not the jobs that make them up,
so we only collect full cronjob data. We associate pods of jobs with the parent cronjob
