feat: Search facets

[alexgarel]

• introduce searchalicious-facets and searchalicious-facet-terms components to:
  • display facets
  • add filters to search
• refactor base of results handling in the search-results-ctl mixin
• change API for facets to be more easy to use:
  • add a facets parameter
  • return easier to parse facets results

Limitations:

• categories_tags seems not to work (but it's a backend problem)
• we need the API to send back selected value because they may disapear while crossed with full text, so user won't be able to uncheck them ! (but first backend must support it)
• for now only the "terms" api is supported, and facet is always sorted by count (while it could be sorted by name for nutri-score for example)

Cool! It would be nice to have a "Apply new filters" button that appears below the facets, as it's not intuitive that we need to click on the search button again to apply them.

Yes, in another PR ;-)

It's possible to updates results when you check any filter

I personally don't like it much because it makes it hard to select two filters at once…
