DesiredStateRepository class abstract

Persists the state each node is supposed to be in.

The Hub's other repositories record what happened; this one records what is meant to be true. The difference between the two is drift, and being able to ask for it — rather than re-applying a preset and hoping — is the whole point of declaring a state at all.
