2b8cc3a93f Lock nodes to avoid simultaneous introspection requests
Now a NodeInfo object has a lock instance attached, which is associated
with a node UUID. New calls acquire_lock and release_lock are added.
NodeInfo.find_node now always acquire a lock, get_node does it optionally.
NodeInfo.finished now always release a lock.

Note that this change does not make NodeInfo thread-safe. Rather it's
preventing simultaneous operations on the same node.

Implements: blueprint node-state
