HONEYCOMB-255 - Cutting identifiers to prevent failing of reverts
Mapping allready processes changes for reverting by InstanceIdentifier instead of using KeyedInstanceIdentifier(to prevent failing to identify handleable nodes) Modified logging to prevent double/triple logging of detailed cause of failed bulk update Reusing WriteContext for revert(removed try with resource to prevent closing of write context before revert) Change-Id: Ie939ebe443629f9cdad5b5b449aa8c5dac40ea67 Signed-off-by: Jan Srnicek <jsrnicek@cisco.com> Signed-off-by: Maros Marsalek <mmarsale@cisco.com>
