Looked into the resources recovery code, and found that we use 
`ResourcesState::recover` function, in which we use 
`::protobuf::read<Resource>` to read the `Resource` object stored on the 
checkpoint file. I don't know whether the format stored on the checkpoint file 
but I do know that we don't use the `Resources::parse` function which is what 
we care about :)
