Add pagination on tasks

[bamthomas]

Is your feature request related to a problem? Please describe.

For now it is not possible to paginate tasks with the endpoint /api/task/all other than task name.

Describe the solution you'd like

It should be possible to paginate the tasks like we did with batch searches.

public class WebQueryPagination {
    public final String sort;
    public final String order;
    public final int from;
    public final int size;
}
