Description

Currently org.apache.ignite.compute.IgniteCompute have follow API

<R> CompletableFuture<R> executeAsync(...); 

In this task we need to inroduce JobExecution interface 

public interface JobExecution<T> {    
    CompletableStage<T> resultAsync();
    
    CompletableStage<JobStatus> statusAsync();
    
    default CompletableStage<UUID> idAsync() {    
        return status().thenApply(status -> status.id());   
    }

    CompletableStage<Boolean> cancelAsync();

    CompletableStage<Boolean> changePriority(long newPriority);
} 

 and modify public API 

 <R> JobExecution<R> executeAsync(...); 

Important note

Implementation of JobExecution interface on clients-side can be done in follow-up tickets. But changes made in this ticket should be backward compatibility.
