Sorting and filtering in Search preview

[bsurai]

At the moment we are allowed to select an index and to enter a search text in the search preview. It would be convenient to be able to set in UI client:

• order, if an index has sortable attributes;
• filters, if an index has filterable attributes.

Hi @bsurai,

Thanks for the suggestion; I've transferred it to the right repository. meilisearch/mini-dashboard#305
