VOL-4154: Changes to techprofile module for etcd storage improvements.
- using protobuf definitions of techprofile template and instance
- store smaller footprint resource instance on the kv store
- store techprofile instance in cache
- reconcile techprofile instance from resource instance on adapter restart
- retry etcd get/put/delete on failure
- remove dealing of onu-gem-info data from PONResourceManager module
  as adapter has to deal with this.
