Ticket 48972 - remove old pwp code that adds/removes ACIs
Bug Description: Old legacy code is still present in the DS that used
to enforce the password policy "user may change password"
using ACIs. This old code would re-add the ACI for
selfwrite on userpassword at server startup.
Fix Description: The current password policy does not depend on these access
access control rules to enforce if a user can change their
password or not.
