    Document token hash algorithm option
    
    With https://review.openstack.org/#/c/116509/ ,
    django-openstack-auth will support a new option for the token hash
    algorithm. This adds the documentation to Horizon's local settings
    example file.
    
    This is for security hardening. The token hash algorithm defaults
    to MD5, which is considered too weak due to the potential for hash
    collisions. Some security standards require a SHA2 hash algorithm to
    be used.
