/**
* Temporary method that allows turning a {@link NodeView} into a {@link DiscoveryNode}. This representation will never be used in
* practice, because in >= 6.4 a consumer of the response will only be able to retrieve a representation of {@link NodeView}
* objects.
*
* Effectively this will be used to hold the state of the object in 6.x so there is no need to have 2 backing objects that
* represent the state of the Response. In practice these will always be read by a consumer as a NodeView, but it eases the
* transition to master which will not contain any representation of a {@link DiscoveryNode}.
