We generally try to avoid global variables, but in this case, it may be helpful to set the component registry as a global variable. We need the component registry to determine the ZK data model API version. It's relatively straightforward to pass it through the zkcontext for zkobjects, but we also may need it in other places where we might alter processing of data we previously got from zk (eg, the semaphore cleanup). Or we might need it in serialize or deserialize methods of non-zkobjects (for example, ChangeKey). To account for all potential future uses, instantiate a global singleton object which holds a registry and use that instead of local-scoped component registry objects. We also add a clear method so that we can be sure unit tests start with clean data. Change-Id: Ib764dbc3a3fe39ad6d70d4807b8035777d727d93
