Re-implement access control using an updated model.

The new model is based on permssions, privileges and roles.
Most importantly it corrects the reverse membership that caused problems
in the previous implementation. You add permission to privileges and
privileges to roles, not the other way around (even though it works that
way behind the scenes).

A permission object is a combination of a simple group and an aci.
The linkage between the aci and the permission is the description of
the permission. This shows as the name/description of the aci.

ldap:///self and groups granting groups (v1-style) are not supported by
this model (it will be provided separately).

This makes the aci plugin internal only.

-Rolegroups
-
-A rolegroup is used for fine-grained delegation. Access control rules
-(ACIs) grant permission to perform given tasks (add a user, modify a group,
-etc.), to task groups. Rolegroups are members of taskgroups, giving them
-permission to perform the task.
-
-The logic behind ACIs and rolegroups proceeds as follows:
-
- ACIs grants permission to taskgroup
- rolegroups are members of taskgroups
- users, groups, hosts and hostgroups are members of rolegroups
-
-Rolegroups can contain both hosts and hostgroups, enabling
-operations using the host service principal associated with a machine.
-
-Rolegroups can not contain other rolegroups.
-
-EXAMPLES:
-
- Add a new rolegroup:
-   ipa rolegroup-add --desc="Junior-level admin" junioradmin
-
- Add this role to some tasks:
-   ipa taskgroup-add-member --rolegroups=junioradmin addusers
-   ipa taskgroup-add-member --rolegroups=junioradmin change_password
-   ipa taskgroup-add-member --rolegroups=junioradmin add_user_to_default_group
-
- Yes, this can seem backwards. The taskgroup is the entry that is granted
- permissions by the ACIs. By adding a rolegroup as a member of a taskgroup
- it inherits those permissions.
-
- Add a group of users to this role:
-   ipa group-add --desc="User admins" useradmins
-   ipa rolegroup-add-member --groups=useradmins junioradmin
-
- Display information about a rolegroup:
-   ipa rolegroup-show junioradmin
