Add collection:searchSpecifications

[y-abs]

What does this PR do ?

This PR adds collection:searchSpecifications with its units tests.

Sample code :

import io.kuzzle.sdk.*;
import io.kuzzle.sdk.CoreClasses.Responses.Response;
import io.kuzzle.sdk.CoreClasses.SearchResult;
import io.kuzzle.sdk.Options.SearchOptions;
import io.kuzzle.sdk.Options.KuzzleOptions;
import io.kuzzle.sdk.Options.Protocol.WebSocketOptions;
import io.kuzzle.sdk.Options.SearchOptions;
import io.kuzzle.sdk.Protocol.WebSocket;

import java.util.ArrayList;
import java.util.concurrent.ConcurrentHashMap;

public class searchSpecifications {
    private static Kuzzle kuzzle;

    public static void main(String[] args) {
        WebSocketOptions opts = new WebSocketOptions();
        opts.setAutoReconnect(true).setConnectionTimeout(42000);

        try {
            WebSocket ws = new WebSocket("localhost", opts);

            kuzzle = new Kuzzle(ws, (KuzzleOptions) null);
            kuzzle.connect();
            

            ConcurrentHashMap<String, Object> searchQuery = new ConcurrentHashMap<>();
            ConcurrentHashMap<String, Object> filters = new ConcurrentHashMap<>();
            ConcurrentHashMap<String, Object> boost = new ConcurrentHashMap<>();

            boost.put("boost", 1);
            filters.put("match_all", boost);
            searchQuery.put("query", filters);

            SearchOptions options = new SearchOptions();
            options.setSize(50);
            options.setFrom(0);
            options.setScroll("10s");

            SearchResult result = kuzzle
                 .getCollectionController()
                 .searchSpecifications(searchQuery, options).get();

            System.out.println(result.hits);
        }  catch (Exception e) {
            e.printStackTrace();
        }
        kuzzle.disconnect();
    }
};

How should this be manually tested?

Correct how refresh option is passed and adapt tests

Why do you use boost ?

That se same example as the js sdk

IMHO you can remove it, it will confuse the user I think
