*
* This class provides strategies on how the DomainApplicationManager
* should deploy an deployment plan at domain-level. This is achieved
* by providing mappings from deployment destination names to actually
* NodeManager daemon IORs, and the strategy for which default NodeManager
* daemons a deployment mechanism should use.
*
* This is a trivial implementation of the deployment configuration
* strategy. We can enhance this class later on to provide
* different deployment location strategies, such as naming service.
