    Introducing node introspection state management

    Currently, state of a node introspection isn't kept in the database.
    This change introduces:

    * a new database column to keep the node introspection state
    * an automaton to manage the node introspection state
    * a decorator to declare a function performing an introspection state
      transition
    * a version_id column is added, to enhance database consistency, that
      is consulted whenever node_info is committed

    This change is part of the HA_Inspector effort[1]
