> In HDDS-2197, the queryNode API call was changed to allow operational state
> (in_service, decommissioning etc) to be passed along with the node health
> state. This changed allowed for a null state to indicate a wildcard, so
> passing:
> opState = null
> healthState = HEALTHY
> Allows one to find all the healthy nodes, irrespective of their opState.
> However, for an enum protobuf field, if no value is specified, the first enum
> in the set is returned as the default. This means that when a null is passed
> for opState, only the IN_SERVICE nodes are returned. Similar for health state
> - passing a null will return only HEALTHY nodes.
> This PR will fix this issue so the null value acts as a wildcard as intended.
