Description

See related discussion on dev list entitled Proper collocation of computations and data (http://apache-ignite-developers.2346864.n4.nabble.com/Proper-collocation-of-computations-and-data-td16945.html).

We must repair data affinity routing for compute jobs. It should work same as for affinityCall/Run with partition.

Currently, ComputeTask map method returns Map<? extends ComputeJob, ClusterNode>,
but we have to provide some API allows to map ComputeJobs to partitions or keys.
This can be done using AffinityKeyMapped annotation or any other way.

Since that's a publiс API any fixes should be discussed on dev list prior to implementation.
