serialization: Use Cereal NVP

This commit modifies the serialization APIs to start utilizing
Cereal's name-value pair (NVP) feature to store to and load from
the JSONs where the interface data is persisted.

Using NVP enables us to add/remove properties to interfaces
without breaking de-serialization.

Since we need to be able to handle both old mechanism of not
using NVP as well as the new one, this commit also bumps up the
Cereal class version to 2 by default. The load functions then look
at the version to decide how best to load the object. The save
functions always store with NVP.

Tested:
Verified the serialized JSONs contained NVP type data.
Verified that the new code is still able to load the
old JSONs.
