storage: Introduce VolumeManifest.operation context When performing datapath operations on a volume (eg. copying data) we mark the volume ILLEGAL before starting the operation and only mark the volume LEGAL again once the operation is finished. As long as this is all done with the volume lease held the engine can poll the volume from any host to determine if the operation is running (lease held) and can detect an interrupted/failed operation (lease free and volume ILLEGAL). Later this contextmanager will be expanded to support volume generation incrementation when exiting successfully which will also allow engine to determine if an operation was completed successfully. All metadata updates must be performed to a single block with one write in order to ensure atomicity.
