Public bug reported:

The Sentinel object in neutron_lib.constants doesn't return the sentinel
object when used with copy.copy(), but it does with copy.deepcopy().

This behavior is inconsistent as deepcopy keeps the singleton behavior,
but copy doesn't.

For example:
---
import copy

from neutron_lib.constants import Sentinel


singleton = Sentinel()
print(copy.deepcopy(singleton) == copy.copy(singleton))
---

Outputs 'False'.
