Proposal: make ResourceService expose a getAllResources() method #16
Description
Currently com.eurodyn.qlack.fuse.aaa.service.ResourceService does not expose any method to get all available resources without previously knowing their Ids.
Since the respective repository does have the appropriate findAll() method, it would be better to get this functionality directly from the Service. So that we won't have to either use the repository and the mapper or extend QLACK's service ourselves in order to get it.
