VOL-4077: Improve storage usage on etcd
- Do away with unnecessary data storage on etcd if it can be
  reconciled on adapter restart
- For data that needs storage, use lesser footprint if possible
- Use write-through-cache for all data stored on etcd via
  resource manager module
- Use ResourceManager module per interface to localize lock
  contention per PON port
