Review comment:
Removed. It is unnecessary to even try to synchronize it.

+1 garbage object: CompletableFuture.
Lets save objects. Or maybe we should remove execute methods?

Good point, thanks.

Review comment:
CancellableTask does not implement Comparable so we can't use
ConcurrentSkipListSet.
There is no ConcurrentHashSet structure in ApacheIgnite now.
But there is GridConcurrentHashSet (actually it is just a wrapper around
ConcurrentHashMap and, unfortunately, it creates extra objects, but I replace
ConcurrentHashMap with it.
