Rucio token based authentication improvements

Who?

 SRC developers and architects

What?

• Enabled improved behaviour for token-based authentication for data managed with Rucio 
• Needs to consider
  • Some dev work required to push through some outstanding issues/PRs that have arisen + documentation
  • Test updated Rucio version on ESCAPE deployment, and then (assuming it all works) update SKAO Rucio server version
  • Keep an eye on steps that would be needed to make use of planned SKA authentication and authorization infrastructure (AAI): e.g.  https://jira.skatelescope.org/browse/SP-1776 
• Possibly includes a spike to test Ceph-S3 storage endpoint integration (https://docs.google.com/document/d/1ofV5iIgpCKCnANNuqIavN_6FvvMTE6QPtQKK_n1P3SE/edit)

Why?

Maintain momentum on this within wider Rucio development and user communities to ensure that this becomes a widely accepted means of providing AAI with Rucio. Ensure that offering token based auth is an accessible goal for new storage sites that may be onboarded into the Data Lake.
