## Summary by CodeRabbit
- **New Features**
- Tenant resource quotas now accept explicit cpu, memory, and storage
values per namespace.
- Default container limits and requests added via a LimitRange (CPU,
memory, ephemeral storage).
- **Behavior Changes**
- Resource quota output simplified: quotas emitted at the root and
storage limit entries omitted from flattened output.
- **Tests**
- Increased timeouts for VM disk readiness and PVC binding; added
runtime checks validating ResourceQuota and LimitRange defaults.
