The conditions are given as keyword arguments, where each keyword names an
attribute. The keyword value can be a literal, a set, or a callable:
* A literal must match the attribute exactly.
* Given a set or list, the attribute value must be contained within it.
* A callable is called with the attribute value and returns a boolean.
If an attribute is specified as a keyword argument but not present in the
task's attributes, the result is False.
Args:
attributes (dict): The task's attributes object.
kwargs (dict): The conditions the task's attributes must satisfy in
order to match.
Returns:
bool: Whether the task's attributes match the conditions or not.
