Changes

1/2: Addfederation.facetsByIndex to POST /multi-search

The federation field of the POST /multi-search payload is extended with a subfield called facetsByIndex.

facetsByIndex is an object whose fields consist of the association of an index's name to its array of faceted fields for this request.

The index must exist at the time of the search, otherwise index_not_found is returned.

The array of attributes must only contain filterable attributes for the index, otherwise invalid_multi_search_facets is returned.
