v1.9.0

• A brand new visualization included in the plugin: Document Table : This visualization does the same thing than 'Enhanced Table' visualization, but for single documents (not aggregations).
  It especially allows to have enhanced features, compared to a saved search (like column custom labels, custom hits size, custom pagination, computed columns and filter bar)
  Disclaimer: this visualization is available only for Kibana 6.6 and later.
• Add support for Kibana 7.7
• Refactor visualization editor to use Elastic UI
• Add 3 new functions available in computed columns formula:
  • col(indexOrLabel, defaultValue): allow to get a column value or a default value (if column doesn't exist)
  • sumSplitCols(): useful to add a computed column, that contains split cols total.
  • countSplitCols(): useful to add a computed column, that contains split cols average (sumSplitCols()/countSplitCols())
• Add a new computed column option: Compute total using formula
• Fix error notification (miss one in two) on Kibana 7.0+
