John Spray 0c105ef352 storage controller: debug observability endpoints and self-test (#6820) ...

This PR stacks on https://github.com/neondatabase/neon/pull/6814

Observability:
- Because we only persist a subset of our state, and our external API is
pretty high level, it can be hard to get at the detail of what's going
on internally (e.g. the IntentState of a shard).
- Add debug endpoints for getting a full dump of all TenantState and
SchedulerNode objects
- Enrich the /control/v1/node listing endpoint to include full in-memory
detail of `Node` rather than just the `NodePersistence` subset

Consistency checks:
- The storage controller maintains separate in-memory and on-disk
states, by design. To catch subtle bugs, it is useful to occasionally
cross-check these.
- The Scheduler maintains reference counts for shard->node
relationships, which could drift if there was a bug in IntentState:
exhausively cross check them in tests.
