Add rebuild task to memberof plugin
This task allows us to rebuild memberuid and memberof attributes throughout the database. This way we can upgrade from version 0.4 databases that didn't generate and store memberuid. The task can be invoked by adding a speaicl named entry to the ldb file. The entry dn to use is: @MEMBEROF-REBUILD, the entry has no attributes and any attribute is ignored at present. The entry will not be stored in the database but will just trigger the task to execute a rebuild of the memberof and memberuid attributes
