abd59fda2d lookup localNodeID in r.Endpoint.Nodes
and refactor the connection{} construction so we can add some
explanation of what is going on here.

cf4eee11a7 fix internet connection counts
For counting we were using a table keyed on a struct containing Node
pointers. For connections between ordinary nodes this works just
fine. But for connections to/from the Internet node we want to track
individual address/port combinations, which involves an extra
lookup. Since our data structures generally contain values, not
pointers, this produces aliases. As a result n connections from/to a
node to/from a specific Internet IP+port would result in n rows in the
count table, each with a count of 1, instead of one row with a count of
n.

Things wouldn't be so bad if it was actually rendered like that -
annoying, but at least accurate - but...

Each row has an ID which is computed from the node IDs and ports. Not
Node references. The ID must be unique - the frontend will only
render *one* thing per ID. Since the row IDs of our n rows are all the
same, we see one row with a count of 1 instead of n rows with a count of
1.

Furthermore, since the frontend's table row limiting is counting rows,
not unique row IDs, a) fewer rows would be rendered than expected, and
b) the displayed count of the number of extra rows would be too high.

The fix is to replace the Node pointers in the key with Node IDs. This
does require an extra table lookup when we come to produce the rows, but
that is just a fairly cheap map lookup.

Fixes #1495.

9e092f1a4a Switch to LatestMap-style node controls
This allows plugins to add controls to nodes that already have some
controls set by other plugin. Previously only the last plugin that
sets the controls in the node would have its controls visible. That
was because of NodeControls' Merge function that actually weren't
merging data from two inputs, but rather returning data that was newer
and discarding the older one.

d0b99969ea Grid-mode tuning!
- Change scrolling behaviour to lock headers in place
- Enable filtering (hitting enter in the search bar) in grid-mode
- Little more top-margin for k8s (can have 3 topos) + taller rows.
- Trying out rank-color + node.relatives in the grid-mode
- First pass at selecting rows.
  - Needs a bit more a fiddle, colors + click areas
- Store grid sort direction (asc/desc) in url state
- Simplify node selection to one method. (over-ride existing card)
  - Remove clicking on name directly (links) to overlay new cards for now.
- Playing w/ grid-mode-toggle icons and labels
- Improves rendering in ff, change of shortcut keys for grid-mode-toggle
- Playing w/ clearer selection colors for grid-mode
- Slight change to selection-ui
- Fixes showNodeInTopology button visibility on the details-panel
  - Was using an old heuristic. Table-mode allows you to open child cards
    before the parent.
- Make it clear what the default sort is in tables
  - E.g. always show a sorting caret
- Sort grid-mode columns, first meta then metrics
- dancing-nodes rememdy #1: pause updates onRowHover
- Splits relatives out into their own columns
- Take into account scrollbar width for grid-mode col header position
- Tooltips on table column headers
- grid-mode: fixes first column headers (proc/container/c-by-image)
- Disable pause-on-hover, too aggresive
- reduce label column width a bit (33pc -> 25pc) for big tables
- Filter grid-mode onSearchChange
  - Rather than previous behaviour of waiting for an <enter>
- Show label_minor on pseudo nodes, that might not have much other info
- grid-mode: further reduce width of id column.
- Fixes go tests, properly moves parents into node-summary
- Fixes sorting of string columns w/ missing fields.
  - E.g. uptime. Where -1e-10 > '3days' doesn't work.

1091225bf6 get rid of Node.Copy()
A shallow copy is sufficient. Which we get for free in most cases
since Node is passed around by value.

8a950a59d6 Remove Metric Add() method
* Helps reduce garbage (MakeMetric() now takes a slice and there's a shorter version MakeSingletonMetric())
* Fixes bug computing Max (Min) in samples since using MakeMetric()
  was causing a default Max/Min of zero.
* Simplifies code a bit
