SPI-15: Configure notifications regarding resource allocations and individual users

Executive Summary: 
A service provider needs to configure receipt and processing of notifications about new allocations and individual users on a resource so the SP can establish accounts on the resource for each allocation. We assume the service provider participates in a public research computing community that allocates resource use to specific individuals, teams, or projects.
User Importance Summary: 
Public research computing communities often allocate use of the community's resources to specific teams or projects. Service providers who operate resources need to receive notifications when new allocations are granted and when new individuals need access to the resource.
