## Summary This PR introduces the new color mapping feature into Lens. The color mapping feature is introduced as a standalone sharable component available from `@kbn/coloring`. The [README.md](https://github.com/elastic/kibana/blob/ddd216457d66912de43c7688ae99044c2c34bbd2/packages/kbn-coloring/src/shared_components/color_mapping/README.md) file describes the components and the logic behind it. The Color Mapping component is also connected to Lens and is available in the following charts: - XY (you can specify the mappings from a breakdown dimension - Partition (you can specify the mappings from the main slice/group by dimension) - Tag cloud (you can specify the mappings from the tags dimension) This MVP feature will be released under the Tech Preview flag. This PR needs to prove the user experience and the ease of use. UI styles, design improvements and embellishments will be released in subsequent PRs. The current MVP-provided palettes are just a placeholder. I'm coordinating with @gvnmagni for a final set of palettes. close #155037 close #6480 fix #28618 fix #96044 fix #101942 fix #112839 fix #116634 ## Release note This feature introduces the ability to change and map colors to break down dimensions in Lens. The feature provides an improved way to specify colors and their association with categories by giving the user a predefined set of color choices or customized one that drives the user toward a correct color selection. It provides ways to pick new colors and generate gradients. This feature is in Tech Preview and is enabled by default on every new visualization but can be turned off at will.

Describe the feature:
Add a text box above the color palette where you can enter the hex code
Describe a specific use case for the feature:
If I want to change the colors for a bar chart, histogram, or other visualization, I have to choose from the limited color palette or I have to look through the visualization URL and change the hex value as described here. It should really be easier to enter the hex code.
