We're going to need a bunch of stuff out of StoragePartitionImpl:
-network_context()
-GetAppCacheService()

And in future CLs, blob/filesystem and other getters out of it.

Can you make Initialize take a StoragePartitionImpl* and move these few lines
above inside of it? Then as we add more support to network service code path we
don't have to change this file or the Initialize() method
