Lens should use the unified metric renderer as well. To make this possible, some additional functionality has to be added to the unified renderer:

• Auto sizing - [MetricVis] Add auto scale functionality to metric unified renderer #124811
• Possibility to apply color background for whole container - [MetricVis] Add possibility to apply color background for whole container in metric #125217
  • This setting should only take effect as long as no small multiples are used. We will get back to this later when introducing small multiples for Lens metric visualizations
• Possibility to configure label font and position (top/bottom) - [MetricVis] Add possibility to configure label font and position in metric unified renderer #125251
• Using formatting from the table if we didn't provide formatter in metric arg - blocked by [Expression] Problem with formatting when we use vis_dimension type as arg #125797
