[Lens] Use Lens in sample data

[flash1293]

To make Lens more prominent within Kibana, sample data visualizations should be replaced by Lens step by step. There is no deadline to finish this process, it can happen incrementally over time when it makes sense.

The following list highlights whether it's possible to replace it with the current Lens feature set and can be used as a guide when to replace which

The sample dashboards mostly exist to show off the features of Kibana, so there's a mix of every feature that Kibana can do. Instead of focusing on replacing the existing panels 1-for-1 I think we should focus on highlighting the new Lens features in the sample data. For example, we can highlight the new table features, show a week over week comparison, or perform a filter ratio.

It might also be time to remove some of the panels in the sample dashboards that are highlighting bad practices. For example, instead of waiting for Lens to support bubble charts, we could add a panel that highlights a Lens feature.

Some notes discussed offline:

• It's fine to add the lens panels directly in sample data
• Remove gauges to make room for Lens features
• Add a tree map
• The dataviz team can assist following good practices here
