2ba50b8b3d Update golang.org/x/net/context to latest 
```
$ gvt delete golang.org/x/net/context
$ gvt fetch golang.org/x/net/context
2018/07/23 18:03:49 Fetching: golang.org/x/net/context
$ git grep -l "golang.org/x/net/context" | grep -v vendor | xargs sed -i '' 's:golang.org/x/net/context:context:g'
$ git grep -l "context/ctxhttp" | grep -v vendor | xargs sed -i '' 's:context/ctxhttp:golang.org/x/net/context/ctxhttp:g'

fixed a bunch of:
```
cannot use func literal (type func("github.com/weaveworks/scope/vendor/golang.org/x/net/context".Context) error) as type func("context".Context) error
```

14dc98343e Use newer gzip handler for performance 
"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"

1706746a32 Faster report merging through mutating objects 
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.

d26b2c3805 Add Kubernetes storage class resource to weave scope 
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.

710d665c41 Upgrade k8s.io/client-go to kubernetes-1.9.1 
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.

d3c53bacd6 'updateKubeFilters` returns early if there are no namespaces

d1bb4aa45e refactor: remove APITopologyDesc.filter 
It's always set to render.FilterUnconnectedPseudo, so we can simply
use that constant in the one function (RendererForTopology) that
looked at that value.

ec7c468758 make it possible for users to see unconnected processes 
We prevented this because rendering them was expensive. It still is,
but less so and actually works well, especially in table mode.

286453b9a9 refactor: move RenderContext where it belongs 
It shouldn't be in 'report' because that is shared between the probe
and the app, and RenderContext, as the name suggests, is only needed
in the app.

70d84170d6 introduce a cheap /api/probes?sparse variant 
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.

72b9e9c6b9 add Reporter.HasReports() for cheap report availability checking 
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.

d528292cd4 make report upgrading fast when it's a no-op 
The vast majority of the cost is memory allocation, so doing a first
pass to see whether any upgrading is necessary at all, and thus
avoiding allocation when it isn't, is a massive saving.
