[Lens Embeddable] Expose colors to consumers

[kertal]

Describe the feature: For enabling consumers of the Lens Embeddable to get the actual configured colors and the linked aggregation values, the Lens Embeddable need to expose these configuration to the consumer, so it can be used e.g. to color rows containing one of the configured aggregation values with the matching colors

Describe a specific use case for the feature:

There's a task in our Discover redesign work where this is a requirement

I've got a question dear @elastic/kibana-visualizations , let's say we already know the values of the aggregation, e.g. a defined set of log levels, dark red -> critical, red -> error, ... would it be already possible to configure Lens in Discover with this colors? So we could use the same colors in the data table.

yes you could. If you are using a breakdown by to get the log levels displayed then you can use/configure color mapping for doing that.
