In order to cache changes in Zookeeper we need to make change objects JSON serializable. This means that we can no longer reference other change objects directly. Instead we will use a cache key consisting of the connection name and a connection specific cache key. Those cache keys can be resolved by getting the source instance using the connection name and then retrieving the change instance via the new `getChangeByKey()` interface. The pipeline manager provides a helper method for resolving a list of cache keys. Cache keys that where resolved once are also cached by the manager as long as the reference is needed by any change in the pipeline. The cache will be cleaned up at the end of a run of the queue processor. Until we can run multiple schedulers the change cache in the pipeline manager will avoid hitting Zookeeper every time we resolve a cache key. Later on when we have the pipeline state in Zookeeper we probably want to clear the change cache in the pipeline manager at the end of the queue processor. This way we make sure the change is recent enough when we start processing a pipeline. Change-Id: I09845d65864edc0e54af5f24d3c7be8fe2f7a919
