Description

IGNITE-7109 adds async cache operations, but query methods remain synchronous.

We should look for ideas at Entity Framework ToListAsync and ToArrayAsync .

1. Create IAsyncQueryCursor and IAsyncFieldsQueryCursor interfaces:

    public interface IAsyncQueryCursor<T> : IQueryCursor<T>
    {
        Task<IList<T>> GetAllAsync();
    }

2. Provide async counterparts for queries: Task<IAsyncQueryCursor> ICacheClient.QueryAsync(...)

This way both initial query and data retrieval can be made asynchronous.
