Description of the Change

This adds a filter to integrate_search_queries() in case someone wanted to filter how they wanted to integrate their search queries. For example, if they wanted search queries with an empty 's' parameter, they should be able to use the filter to do so.

Verification Process

1. Apply PR
2. Add the filter:

add_filter( 'ep_integrate_search_queries', 'empty_search_integrated_request', 10, 2 );

function empty_search_integrated_request( $enabled, $query ) {
	if ( empty( $query->query_vars['s'] ) ) {
		$enabled = true;
	}

	return $enabled;
}

3. Go to an empty search page aka example.com/?s=
4. Expect to see search query offloaded still
