Add color swatches support

[pkarw]

What is the motivation for adding / enhancing this feature?

Currently, we're displaying the color options using the color attribute label. This is pretty limiting as in Magento2 users can define even picture based color swatches.

M2 API doesn't return the swatches. So the first problem is to work around this issue - maybe even adding custom magento2 api option. Then we need to extend ColorSelector.vue to use the swatch values properly

What are the acceptance criteria

• color swatches displayed as defined in the Magento2 admin panel

Can you complete this feature request by yourself?
