Add plugin for manage self-service ACIs

This is just a thin wrapper around the aci plugin, controlling what

+Self-Service Permissions
+
+A permission enables fine-grained delegation of permissions. Access Control
+Rules, or instructions (ACIs), grant permission to permissions to perform
+given tasks such as adding a user, modifying a group, etc.
+
+A Self-Service permission defines what an object can change in its own entry.
+
+
+EXAMPLES:
+
+ Add a self-service rule to allow users to manage their address:
+   ipa selfservice-add --permissions=write --attrs=street,postalCode,l,c,st "User's manage their own address"
+
+ When managing the list of attributes you need to include all attributes
+ in the list, including existing ones. Add telephoneNumber to the list:
+   ipa selfservice-mod --attrs=street,postalCode,l,c,st,telephoneNumber "User's manage their own address"
+
+ Display our updated rule:
+   ipa selfservice-show "User's manage their own address"
+
+ Delete a rule:
+   ipa selfservice-del "User's manage their own address"
