So that, if many shortcut reports are produced in quick succession,
they will tend to get merged together.
Expand the queue size for shortcut reports, to avoid holding up the
producer so much.

5) probe/process/walker_linux_test.go & 6) tools/lint
1)'backend/Dockerfile' : Conditional added so that the cross-compiling should
be done on amd64. Also removed support for sh-lint for ppc64le for now.
As the version for shfmt mentioned in the dockerfile is not available for
ppc64le and the later version does't work fine with existing application.
2)'probe/endpoint/dns_snooper.go' : Renamed this file so as to reuse for ppc64le
and added a build-constraint. Now this file will be build for amd64 on linux
and ppc64le on linux.
3)'client/Dockerfile' : Modified the version of the base image for node from
8.4.0 to 8.11, as this version supports multiarch.
4)'docker/Dockerfile.cloud-agent' : Modified the version of the base image for
golang from 1.10.2-strech to 1.10.2, which supports multiarch.
5) 'probe/process/walker_linux_test.go' : Test fixed to run for ppc64le,
modified the code to accept RSSBytes based on pageSize value per
architecture, instead of hard-coded values.
6)'tools/lint' : Modified the file to skip the sh-lint implementation for ppc64le.

When the probe.cri is enabled the CRI probe will be used to gather
the container information via the CRI API. For now only the basic
information is included in the generated report, those that we can get
via the CRI ListContainersRequest.
This option gives a crude way to view the raw probe data as json in
the container logs, so that you can check exactly what it would have
sent.
We stub out the PipeClient interface with a dummy implementation in
this mode.
Simplification: move the 'noControls' functionality into the probe, as
we don't need a whole struct to do that.
The ReportPublisher interface also moves into probe where it belongs:

- 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.

- Kubernetes storage components such as PV and PVC are connected based on two
parameters Persistent volume claim name and Persistent Volume name.
- PVC contains the volume name which is, PV name itself. Hence, we can
show edge for PVC and PV.
- This will bring higher level visibility for kubernetes storage components.

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.

Removed to reduce CPU and memory usage in probes.
This code was added in August 2016 so that newer probes could be used
with older apps. Since then we have adopted the stance that new apps
will accept reports from old probes but not vice-versa, on a version
change.
Now that we enter the container namespace to fetch IPs for every
container, there is no need to have 'weave ps' do it.
This does mean we lose Weave MAC addresses, but that is a rather
idiosyncratic feature anyway.
With c75700fe04 we added code to detect
Ubuntu Xenial kernels with a regression in the eBPF subsystem in order
to gently fallback to procfs scanning on such systems (and not crash the
host system by running eBPF code).
With the latest kernel update for Ubuntu Xenial, the bug was fixed:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1763454
Therefore we can update the added check with an upper limit and make
sure that eBPF connection tracking only is disabled on kernels within
the range having the bug.

* 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
