* 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.
* 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.
Decoration is in fact quite a simple process that is applied on entry
to rendering: we take a base renderer, transform it with a decorator,
and then render a report with it. The new render.Decorate() function
does exactly that.
There is one exception. When rendering an individual node, e.g. for
showing its details panel in the UI, we must not lose the node during
decoration. That requires some special logic, which previously resided
in the PreciousNodeRenderer, and now lives in handleNode.
scope-app:
* Adds `-app.metrics-graph` cli flag for configuring the base url to
use for graph links; supports :orgID and :query placeholders
* Assigns query URLs to existing metrics and appends empty metrics if missing
scope-ui:
* Extends <CloudFeature /> with option alwaysShow
* Adds <CloudLink /> to simplify routing when in cloud vs not in cloud
* Links metric graphs in the ui's node details view for all k8s
toplogies and containers so far
* Tracks metric graph click in mixpanel `scope.node.metric.click`
* Uses percentages and MB for CPU/Memory urls
* Passes timetravel timestamp to cortex in deeplink
gofmt load_container_filters.go
removed the environment variable for container label filters
Added the --app.container-label-filter command line argument, and load_container_filters.go now uses the results from that
Changed init() to InitializeTopologies()
Changed init() to InitializeTopologies() so that it can be called after the container filters are loaded from the command line argument. init() executes before main() in prog/main.go, so the flag parsing isn't finished before init() is called
Applied lint fixes
fixed lint issues
brought back the init function for api_topologies.go
Addressed many of the PR comments, except escaping colons
Renamed IsDesired to HasLabel in render/filters.go
Allows for the user to escape colons
added registry function for modifying the container filters
created a separate function that parses the container filter flags
simplified registry.addContainerFilters()
addressed review comments
switched API Topology Description IDs to constants
addressed review comments
joined constants
added test functions
addressed most of the review comments
Changed containerLabelFilters to an array of APItopologyOptions, placing the parsing in the Set() function. Removed parsing from HasLabel in render/filters.go
refactored code
added test that applies to the container filtering by labels
applied golint
made Registry items private and added a MakeRegistry() function
fixed usage of topologyRegistry.RendererForTopology
Added container label filters by exclusion
minor update to report_fixture
Modified container labels test to use existing report
I added labels to the existing containers in the fixed report for testing.

Addressed final review comments
* Remove individually vendored k8s.io/kubernetes/pkg/<foo>
* Vendor the whole of vendor/k8s.io/kubernetes/pkg
* Add k8s pod log control
* Tag pods with host id and include them in the host topology as children.
* adding a basic test for kubernetes.Reporter.GetLogs
* New encoding format:
* Msgpack reports between probe<->app (smaller representation, faster to
encode/decode).
* Still use JSON between app<->UI (try to avoid making javascript deal with
mspack).
The app still suports publishing reports in both gob and JSON, not braking
backwards compatibility.
* Use compile-time generated marshallers/unmarshallers for higher performance. In
order to be able to skip code-generation for certain types, I included
https://github.com/2opremio/go-1/tree/master/codec/codecgen instead of
upstream until https://github.com/ugorji/go/pull/139 is merged.
* Encode/decode intermediate types using github.com/ugorji/go/codec.Selfer
for higher performance and reducing garbage collection (no temporary buffers).
* Added helper for installing scope on gcloud
* Added topologies Pods and Pods-by-Service
* Uses k8s.io/kubernetes/pkg/client/cache for the client
* Filter kube-system nodes by default
* Only show the k8s topologies if we've received a non-empty k8s report
