VOL-4077: Improve storage usage on etcd
- the onu adapter will now receive the tp instance on the
  inter-container kafka message and need not reach the etcd store
  to fetch it.
- on reconcile, the onu adapter need to go to the kv store to
  fetch the tp instance, but request the tp instance via a new
  API towards openolt adapter which in-turn will fetch from the
  cache.
- re-org the code in onu-metrics-manager to restore pm-data
  on reconcile to avoid panics by accessing uninitialzed data
  if ani-fsm were to try adding gem port for monitoring
  before pm-data is initialized properly.
