HONEYCOMB-431: make DataModification.validate idempotent

This patch modifies contract of DataModification.validate
to make it idempotent.

ModifiableDataTreeManager.validate now invokes dataTree.validate
on a copy of DataTreeModification.

ModifiableDataTreeManager.validateCandidate was introduced
to allow additional validation.
