new response handlers for vislib

[ppisljar]

two response handlers:

• series_data: works with all vislib types except pie (line, area, bar, heatmap. metric, gauge, goal)
• hierarchical_data: works with pie chart

goals:

• decouple vislib from ES response (aggConfigs)
• decouple tooltips from ES response
• decouple event handling (filter, brush, hover) from ES response
• decouple <visualization> from ES response
• provide easy to use data format

as side effect two issues are fixed:
closes #12746
closes #10543

things that are still missing:

• tests for new response handlers

other charts should be converted to use one of the new request handlers as well, probably the third one will need to be added (table_data)

using visualizations is now fairly easy as the data object is no longer coupled to elastic search.

const myVis = new Vis(indexPattern, 'bar');
const myData = {
  charts: [{
    label: 'my chart label',
    series: [{
      label: 'Count',
      values: [{ x: 'a', y: 120}, { x: 'b', y: 80 }, { x: 'c', y: 140 }]
    }]
  }]
};

<visualization vis=myVis data=myData></visualization>

Discover date histogram does not show extended bounds. Notice in the screen shot that the user is asking for the last 30 days yet the timeline only shows the last couple of days, 07-24 to 07-27. The same behavior occurs with a vertical bar chart split on date_histogram visualization.

No tooltip and console error exist when you first create a pie chart visualization

Looks really good.

As long as you are updating all of the fixtures, how about exporting a named object instead of default?

Update comment for hierarchical response

[ppisljar]

this should probably be {{y}} or similar

[ppisljar]

closing, will reimplement but based on tabify resposne not es response
