This gerrit (https://git.opendaylight.org/gerrit/#/c/12511/) moved all the code which was at the top-level of the controller repo under opendaylight to opendaylight/adsal. This included the extras features which are not neccessarily specific to adsal. In fact they have more to do with mdsal because it contains the akka related features. This stuff either needs to be moved out to some common features directory or to mdsal.
