Description

GridDhtLockRequest#addNearKey(KeyCacheObject) does not have any usage, i.e. GridDhtLockRequest#nearKeys is not updated at all.

So, nearKeys always returns empty collection and, moreover, some code becomes useless, eg. GridNearTransactionalCache#startRemoteTx(UUID, GridDhtLockRequest) [1], etc.

We have to figure out whether this is redundant code or whether we have lost some useful functionality.
