This is a first pass at something analogous to swift's diskfile. The API is probably not finalized. There are a few interfaces you have to implement for a new ObjectEngine. There's also a RegisterObjectEngine function to register a new object engine. See go/objectserver/objengine.go for information. I had to rejigger the AtomicFileWriter interface to make them friends, but this way is fine too. Change-Id: I032038b5e8a068aecdf8b29631f60ebf00cfb2ee
