The following methods can inspect config or a node in a config

# Optional fields can be assigned None
def is_optional(obj: Any, key: Optional[Union[int, str]] = None) -> bool:

# None fields, well - are None. None fields still have a type (int, dict, etc)
def is_none(obj: Any, key: Optional[Union[int, str]] = None) -> bool:

# True if the node is an interpolation
def is_interpolation(node: Node, key: Optional[Union[int, str]] = None) -> bool:

# True if the node is missing ('???').
def is_missing(cfg: BaseContainer, key: Union[int, str]) -> bool:
