> Currently, the Resources / Resource_ wrappers do not have move support. Since copying resources are rather expensive (especially when there's large ports ranges or metadata like reservations / labels), we should add move support to reduce copying automatically where possible:
> * Constructors for both Resources and Resource_
> * +, +=, addition operations: with addition we sometimes need to add the resource to the vector in which case we can move if taking an rvalue
