Title:
Hints with values of None seem to be broken
Status in OpenStack Identity (keystone):
Fix Released
Bug description:
The Hints object allows developers to construct filters to query the
backend for specific entries. For example, I can ask the backend to
give me a list of entities that match a specific criteria:
hints = driver_hints.Hints()
hints.add_filter('key_hash', primary_key_hash)
credentials = self.credential_api.list_credentials(hints)
The above example should give me all credentials that have a key_hash
column matching the value of primary_key_hash. If I try to apply this
same pattern using None as the value to match, I get an error:

It seems that Hints doesn't allow you to filter a backend by "return
to me all things that have this attribute set to NULL", even though we
expect this to work in our code [0].
