[ZEPPELIN-2217] AdvancedTransformation for Visualization
### What is this PR for?
Even if we already have 2 useful transformation, they have limitations.
- we can't configure axises in `PivotTransformation`
- we can't use aggregator functions in `ColumnselectorTransformation`
`AdvancedTransformation` provides both functionality. Additionally, it
supports
- dynamic parameter panel for configuring charts
- multiple, configurable, detailed axises
- maximizing / minimizing each panel
#### Implementation Details: Configuring Chart
See also: [an example visualization using
AdvancedTransformation](https://github.com/1ambda/zeppelin-advanced-transformation/blob/master/examples/local-test-highcharts-columnrange/index.js)
```javascript
this.spec = {
/** axis spec */
axis: {
'xAxis': { type: 'number', dimension: 'single', group:
false, aggregator: false, },
'yAxis': { type: 'string', dimension: 'multiple', group:
true, aggregator: false, },
},
/** parameter spec */
parameter: {
'xAxisName': { type: 'string', defaultValue: '',
description: 'Name of xAxis', },
'yAxisName': { type: 'string', defaultValue: '',
description: 'Name of yAxis', },
'yAxisUnit': { type: 'string', defaultValue: '',
description: 'Unit of yAxis', },
}
}
this.transformation = new AdvancedTransformation(config, this.spec)
```
#### Implementation Details: return value of `transform`
```javascript
return {
raw: tableData.rows,
grouped: grouped, /** [{ group, groupedRows, aggregated }] */
column: {
allColumns: tableData.columns,
groupColumns: groupColumns,
aggregatedColumns,
normalColumns: normalColumns,
}
}
```
