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
* Add filters for pseudo nodes.
- Don't filter the internet node as a pseudo node.
- Rename pseudo filter to unmanaged/uncontained.
- Review feedback
- Move the FilterFoo funcs into the tests
- Drop the 'nodes' from filter labels.
* Fix experimental
Squash of:
* We have to keep all the container hostnames until the end so we can
count how many we've filtered
* Adding tests for ContainerHostnameRenderer and PodServiceRenderer with
filters
* Because we filter on image name we need the image name before
filtering
* Alternative approach to passing decorators.
* Refactor out some of the decorator capture
* Don't memoise decorated calls to Render
* Fixing filtered counts on containers topology
Tricky, because we need the filters to be silent sometimes (when they're
in the middle), but not when they're at the top, so we take the "top"
filter's stats. However, this means we have to compose all
user-specified filters into a single Filter layer, so we can get all
stats.
There are no more Silent filters, as all filters are silent (unless they
are at the top).
Additionally, I clarified some of the filters as their usage/terminology
was inconsistent and confused. Now Filter(IsFoo, ...) *keeps* only nodes
where IsFoo is true.
Squash of:
- use detailed.Summaries to render topology nodes
- ban merging nodes of different topologies (they should be mapped)
- need to prune parents when mapping node types
- render container images by id if they have no name
- remove separate render ids and prune parents in NewDerived*
- don't render metrics/metadata for groups of nodes
- fixing up tests
- removing pending unit tests (for mapping.go, for now)
- updating experimental dir for RenderableNode removal
- Add interfaces to allow for alternative implementations for Collector, ControlRouter
and PipeRouter.
- Pass contexts on http handlers to these interfaces. Although not used by the current
(local, in-memory) implementations, the idea is this will be used to pass headers to
implementations which support multitenancy (by, for instance, putting an authenticating
reverse proxy in form of the app, and then inspecting the headers of the request for
a used id).
* 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
