CAN-11: Publish resource status updates

Executive Summary: 
An application developer needs to create an application that publishes resource status updates in a best-effort, asynchronous manner. Resource examples include: a computing resource (e.g., a high-performance or high-throughput computing resource), a monitoring service, a scientific instrument (e.g., a sensor network, telescope, microscope), a running simulation, or a web application (e.g., science gateway or user portal). Status information may include: availability information (up/down), service information (active queues, queue length, estimated queue times), progress toward completion (units completed, percent completion).
User Importance Summary: 
Research in many fields is increasingly becoming automated. Automation tools may need access to dynamic status information from resources so they can adapt to changes in the system.
