Object persistence from annotations

[brokad]

Currently the only form of persistence across runs of a service is an (optional) database accessible via Factory.

Maybe we could allow users to "persist" a serializable/deserializable object across runs with a simple derive annotation

#[derive(Serialize, Deserialize, Persist)]
struct MyPersistingState {
  view_counter: usize
}

I'll give this a go!

This was added with the new persist resource in v0.6.0
