   …zation and suggestions panel (elastic#163412)
   
   ## Summary
   
   Related to elastic#163089
   
   Adding the first performance journey for the Lens Editor. It simulated
   loading existing Lens visualisation with data view having 10k fields.
   
   We collect the following metrics:
   - `fetchFieldsExistenceInfo` reports time it takes to fetch fields in
   Data Panel
   - `lensVisualizationRenderTime` reports both time it takes to fetch the
   data (`time_to_data`) and render the main visualization
   (`time_to_render`)
   - `lensSuggestionsRenderTime` reports time it takes to render
   suggestions panel
