When updating node labels and annotations use JSON patches instead of
doing a read-modify-write on the whole node object. Patching is already
being used in managing extended resources so some of the existing code
was re-usable.
This patch should mitigate the problem of node update failures caused by
race conditions (a change in the node object between our read and write)
resulting e.g. in errors/restarts in nfd worker pods.
