9eda27822c Show k8s labels and container env vars in the details panel. (#1342)
* Show k8s labels and container env vars in the details panel.

* Add show more bar to the env vars and labels

* React key was in the wrong place; empty tables render section labels.

2c6b6e6707 Refactoring rendering to remove RenderableNode
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

56122dd0cc Details panel backend redesign
Megasquish:
  [app] remove unused edge endpoint
  [WIP] refactoring node details api endpoint
  [WIP] plumbing the children through the rendering process
  adding IDList.Remove and StringSet.Remove
  [WIP] working on adding parents to detailed node renderings
  WIP UI components with mock backend data for new details
  grouping children by type
  UI components for node details health and info
  metric formatters for details panel
  Column headers and links for details table
  [WIP] started on rendering node metadata and metrics in the detail view
  DetailedNode.LabelMajor -> DetailedNode.Label
  rendering decent labels for parents of detailed nodes
  render metrics onto the top-level detailed node
  removing dead code
  Links to relatives
  metrics have a Format not Unit
  Show more/less actions for tables and relatives
  adjusted metric formatter
  TopologyTagger should tag k8s topology nodes
  make renderablenode ids more consistent, e.g. container:abcd1234
  working on rendering correct summaries for each node
  adding report.Node.Rank, so that merging is independent of order
  rendering children and parents correctly
  output child renderableNode ids, so we can link to them
  add group field to metrics, so they can be grouped
  Refactored details health items to prepare for grouping
  add metrics to processNodeSummaries
  hide summary section if there is no data for it
  fixing up tests
  moving detailed node rendering into a separate package
  Node ID/Topology are fields not metadata
    - This way I think we don't have to care about Metadata being non-commutative.
    - ID and topology are still non-commutative, as I'm not sure how to sanely
  merge them, but it's possible we don't care.
  host memory usage is a filesize, not a percent
  working on fixing some tests
  adding children to hosts detail panel
    - Had to redo how parents are calculated, so that children wouldn't interfere with it
    - have to have the host at the end because it is non-commutative
  only render links for linkable children (i.e. not unconnected processes)
  resolving TODOs
  fixing up lint errors
  make nil a valid value for render.Children so tests are cleaner
  working on backend tests
  make client handle missing metrics property
  Stop rendering container image nodes with process summaries/parents
  fix parent link to container images
  Calculate parents as a set on report.Node (except k8s)
  refactoring detailed.NodeSummary stuff
  removing RenderableNode.Summary*, we already track it on report.Node
  working on tests
  add Columns field to NodeSummaryGroup
  fixing up render/topologies_test
  fix children links to container images
  get children of hosts rendering right
  working on host renderer tests
  Change container report.Node.ID to a1b2c3;<container>
  The id should be globally unique, so we don't need the host id.
    This lets the kubernetes probe return a container node with the pod id,
    which will get merged into the real containers with other reports. The
    catch is that the kubernetes api doesn't tell us which hostname the
    container is running on, so we can't populate the old-style node ids.
  change terminology of system pods and services
  Fix kubernetes services with no selector
  Fixes handling of kubernetes service, which has no pods
  fix parent links for pods/services
  refactor detailed metadata to include sets and latest data
  fixing up host rendering tests
  fleshing out tests for node metadata and metrics
  don't render container pseudo-nodes as processes
  Update test for id format change.

8f63d7be7f Metrics plumbing for reports.

- format memory dynamically to scale
- add some tests for the immutability of metrics
- use ps.List for Sample storage, so it is immutable. Have to implement custom marshalling
- adding tests for report.Metrics
- check the ordering of the json samples
- Make the nil value for Metrics valid.

e1f7752a34 Split PacketCount to Egress and Ingress
Also, 1 packet may be counted in N topologies, so you can't rely on the
sum of all packet counts across topologies having any relation to the
sampling data.

0aadf6447b Revert to correct edge construction
Another implicit invariant in the data model is that edges are always of the
form (local -> remote). That is, the source of an edge must always be a node
that originates from within Scope's domain of visibility. This was evident by
the presence of ingress and egress fields in edge/aggregate metadata.

When building the sniffer, I accidentally and incorrectly violated this
invariant, by constructing distinct edges for (local -> remote) and (remote ->
local), and collapsing ingress and egress byte counts to a single scalar. I
experienced a variety of subtle undefined behavior as a result. See #339.

This change reverts to the old, correct methodology. Consequently the sniffer
needs to be able to find out which side of the sniffed packet is local v.
remote, and to do that it needs access to local networks. I moved the
discovery from the probe/host package into probe/main.go.

As part of that work I discovered that package report also maintains its own,
independent "cache" of local networks. Except it contains only the (optional)
Docker bridge network, if it's been populated by the probe, and it's only used
by the report.Make{Endpoint,Address}NodeID constructors to scope local
addresses. Normally, scoping happens during rendering, and only for pseudo
nodes -- see current LeafMap Render localNetworks. This is pretty convoluted
and should be either be made consistent or heavily commented.
