feat(api)!: ListMixin.list typing overload
BREAKING CHANGE: The `http_list` method will no longer ignore the `iterator` argument if the `page` argument is not None. The `ListMixin.list()` will now return either list or iterator based on the `iterator` argument. This will make certain type narrowing checks redundant. Overload `ListMixin.list` method typing to return either `RESTObjectList` or `list` based on the `iterator` argument. By default then `iterator` is False return a list otherwise return an iterator. Provide 3 overloads: 1. `iterator: Literal[False]` - this is the default and returns a list. 2. `iterator: Literal[True]` - return an iterator. 3. `iterator: bool` - return either list or iterator. It is useful when the list function is being extended by another function that can also take either True or False for the `iterator` argument. Make `page` argument to `http_list` not override the `iterator` to make the function signatures more straight forward. This also makes it easier to unpack `**kwargs` as only `iterator` argument will control if a list or iterator is returned so the `**kwargs` can no longer have a hidden page argument.
