Incorrect relationship declaration in models.ComputeNodeStat

[Mikhail Dubov]

db.sqlalchemy.models.ComputeNodeStat.stats field is not properly named: since it is a relation that maps to db.sqlalchemy.models.ComputeNode, it should be named 'compute_node', not 'stats'. Besides, the call to the relationship() method lacks the foreign_keys parameter.

    Stylistic improvement of models.ComputeNodeStat

    The patch is aimed at improving the readability of models.ComputeNodeStat.

    Here, we rename the 'stats' attribute of the class to 'compute_node' (due to
    the fact that the corresponding relation actually maps to ComputeNode class,
    not to ComputeNodeStat). We also rewrite the relationship() method call to
    make it stylistically conforming with the analogous 'service' relationship
    in the ComputeNode class: we add the 'foreign_keys' parameter, wrap the
    'backref' parameter into a method call and remove the auxiliary 'primary_join'
    variable.
