Options for "unmanaging" certain aspects of configuration

-- DRAFT --

Aspect	Behaviour when added via config	Behaviour when not present in config	Current config options for behaviour	Proposed config option
Users and Groups	are created	not removed	obsolete_authorizables can be used docu	leave as is
Relationships between users and groups within config not leaving the "config space"	are created	are removed	none	none
Relationships of users and groups leaving the "config space" and hence inheriting permissions from elsewhere (isMemberOf)	are created	are removed	keepExistingMembershipsForGroupNamesRegEx: docu	Proposal: unmanagedIsMemberOfRegex on authorizable config. Default in global config defaultUnmanagedIsMemberOfRegex that is taken as default for config beans that do not specify it. If nothing is configured manage everything
Relationships of groups leaving the "config space" and pushing permissions to other, existing authorizables (members)	are created	are removed (if not regular user, regular users are often assigned by user administrators)	unfortunately same as in row above	Proposal: unmanagedMembersRegex on group config. Default in global config defaultUnmanagedMembersRegex that is taken as default for config beans that do not specify it. If nothing is configured manage everything
ACEs for authorizables in the config	are created	are removed	none	Currently discussed in #212 proposing a property ignoreAcesInPaths or restrictAcesRegex - NEW Proposal: unmanagedAcePathsRegex on authorizable config.

IMPORTANT HINT: The "current behaviour change configs" only affect the cleanup. The idea of the proposed unmanagedXXX properties would be that they also prevent creating relationships/ACEs that are explicitly marked as unmanaged by AC Tool Config - that way the create/remove-cycle would be consistent.
