Create Host Memory agent and common bundles
This commit extracts Host Memory data collection from SystemBackend into
a host-memory-agent bundle. It also moves the MemoryStatDAO from
common-core into a host-memory-common bundle that registers the DAO once
Storage is available. This also removes the DAO from DAOFactory.
