    Shadowing a nonlocal_user incorrectly creates a local_user
    
    This patch fixes a bug where when shadowing a nonlocal_user (LDAP,
    custom driver) it also incorrectly creates a local_user. The error is
    related to hybrid properties and calling the class from_dict method,
    which set the local_user attributes.

Title:
  Entry to User table creates entries in local_user table for ldap and
  custom driver users

Status in OpenStack Identity (keystone):
  Fix Released

Bug description:
  This was observed while trying with ldap and custom driver users (not
  sure of the behavior for federated and sql users).

  It's found that after ldap / custom driver user is configured with OpenStack and a user authentication request is placed (token issue for eg.), there are entries made into 3 tables:
  - User
  - local_user
  - nonlocal_user

  As seen below, the ldap user name is avni_u1

  This behavior is probably not new and is caused due to
