While we're there, adopt a consistent ordering for all places that shapes are listed
Order is least sides to most sides, with circle before polygons, and complex shapes (currently just Cloud) after.
On shape choices for topologies:
* Since the k8s logo is a heptagon, we want pods to be heptagons.
* Since triangle is 'a bit weird', we put it on the least-important type, replica sets.
* Pentagons look a little weirder than octogons (it's the lack of symmetry) so we put octogons on the most common (deployments)
* Rendering both nodes and edges from one component.
* Organized the render layers in a more readable manner.
* Rerendering optimization.
* Finer edge rendering layers.
* Moved the constants out of the component file.
* Typo fix.
* Include edge thickness in <Motion /> instead of fade-in effect.
In union option groups, the list of selected ids is encoded as a comma-delimited string.
For example, if 'foo' and 'bar' are selected, the value 'foo,bar' is sent, ie ["foo", "bar"] -> "foo,bar"
Under this scheme, with nothing selected, the empty string should be sent, ie. [] -> ""
Before this change, the frontend code called the "none option" by id 'none'.
There were several issues with this:
* The frontend would send 'none' when nothing was selected, not ''. The backend ignored this as it ignores
junk values in the options, treating them as though they hadn't been given.
* The backend would attempt to set the default value of an option to "nothing selected", ie. [], by sending ''.
The frontend would interpret this as nothing selected, *not even the 'none' option*, which caused a visual bug.
* Everything would break if one of the legitimate options had the id 'none', which could easily happen eg.
if a user had a 'none' k8s namespace. This is perhaps an unusual name, but our code shouldn't break when
a particular arbitary string is used as an input.
With this change, the none option is called '', which fixes all the above problems:
* The frontend encodes [''] as ''
* The frontend decodes '' as [''], and therefore shows the '' option as selected
* The string '' is not a valid k8s namespace name and is a reasonable "prohibited value" for all other use cases.
The backend already couldn't handle a value with this id correctly prior to this change anyway.
* Node details fetching reports at proper timestamp.
* Corrected all the relevant timestamps in the UI.
* Renamed some state variables.
* Time travel works for topologies list.
* Added a whole screen overlay for time travel.
* Polished the backend.
* Make time travel work also with the Resource View.
* Fixed the jest tests.
* Fixed the empty view message for resource view.
* Some naming polishing.
* Addressed the comments.
Pins d3-transition and d3-drag dependencies which were previously
pulled in as deps from d3zoom as version 1.1.0 each. This broke
the zoom feature for `npm start`.

This was confusing in demos at KubeCon and DockerCon this year, as
clicking on nodes kept the UI zooming in.
Plus, when asked, users had no idea that double-click meant zoom in.
