Replace Deprecated `abc` Decorators

Importance	Review Guidance	Requires Scanning Tool
Low	Merge Without Review	No

The @abstractproperty, @abstractclassmethod, and @abstractstaticmethod decorators from abc has been deprecated since Python 3.3. This is because it's possible to use @property, @classmethod, and @staticmethod in combination with @abstractmethod.

Our changes look like the following:

 import abc

 class Foo:
-   @abc.abstractproperty
+   @property
+   @abc.abstractmethod
    def bar():
        ...

and similarly for @abstractclassmethod and @abstractstaticmethod.
