* Pass Go context down to Renderers
This is useful for cancellation or tracing.
* Add tracing spans to app
Also log things like number of nodes in Map, total number of reports.
- Add a new client in probe/kubernetes/client.go
which will be used to fetch details of Snapshot CRD
- Visualize VolumeSnapshot and VolumeSnapshotData
- Add adjacency between PV and VolumeSnapshot
- Add adjacency between VolumeSnapshot and VolumeSnapshotData
- Add snapshot filter to hide and show snapshots

"github.com/NYTimes/gziphandler" keeps a pool of gzip writers, which
saves on garbage-collection.
Also the old one, github.com/PuerkitoBio/ghost, is marked "Status : Unmaintained"
When we know we have the only reference to a Report or Node object we
can avoid copying the data to change it. Add "Unsafe" variants of
various Merge operations which mutate the receiver, and a new Merger
which takes advantage of them.
- 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
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.
It's always set to render.FilterUnconnectedPseudo, so we can simply
use that constant in the one function (RendererForTopology) that
looked at that value.
In many cases we only need to know whether there are _any_ connected
probes, and not the probe details. Obtaining that info is cheaper
since it requires no reading or merging or reports.
This requires no report reading / merging.
We plan to expose this in the HTTP API, so the UI gets a cheap way of
checking whether the app is currently receiving data from probes.
