Understand requirements of SDH&P pipelines (time boxed spike)

Following Stefan Wijnholds' presentation at Olive team workshop, there is scope for more discussion/collaboration between teams in the DP ART and the SRC ART.

Initially the goal of this spike should be to start these discussions to better understand the current state of the SDH&P workflows, and the types of resources they are designed to run on. Documentation and code, capturing the requirements and capabilities of such workflows, should be identified and presented to the wider ART at e.g. a system demo.

We'll have this as a time-boxed spike to deliver improved understanding.
