phases: check secret presence the right way during discovery

There is an official function for this, lets use it.

This will prevent the code to break in the future while we refactor the phase
code.

from typing import Any, NewType, NoReturn, TypeVar, cast

from . import Attribute, _OnSetAttrType

_T = TypeVar("_T")

def frozen(
    instance: Any, attribute: Attribute[Any], new_value: Any
) -> NoReturn: ...
def pipe(*setters: _OnSetAttrType) -> _OnSetAttrType: ...
def validate(instance: Any, attribute: Attribute[_T], new_value: _T) -> _T: ...

# convert is allowed to return Any, because they can be chained using pipe.
def convert(
    instance: Any, attribute: Attribute[Any], new_value: Any
) -> Any: ...

_NoOpType = NewType("_NoOpType", object)
NO_OP: _NoOpType
