Use code in Discovery to create new PersistentStorage bundle

[ghost]

Currently the architecture lifecycle is published in etcd through the discovery interfaces. The discovery interface should be stable and Discoverer.updateProperties should not exist. Instead, a new bundle should be created to store data in the persistent storage and listen to changes. The entire ArchitectureManager should use that bundle instead.

This new PersistentStorage bundle should use the discovery code partially as a lot of functionality is overlapped.
