Allow Airlock Review VMs to access previous airlock requests.

A clear and concise description of what the problem is. Ex. I'm always frustrated when [...]

Often when reviewing airlock requests, we need access to previously accepted or rejected airlock requests.
E.g. Sometimes we have plots where the underlying data was provided in a previous requests.
We also check against issues with different groupings of the same data, that may be differenced to reveal information about a group smaller than our disclosure threshold.

A clear and concise description of what you want to happen.

I want to be able to, on demand, load in / mount data from previous airlock requests in the same workspace.
This includes at least approved, rejected and cancelled.
Cancelled requests are needed as sometimes, partly due to lack of the requested feature, I leave requests open whilst I follow up with some questions, and sometimes those are cancelled by the researchers.

I do not know the best way to achieve this, as the review VM is not operated within the workspace of the request AFAIU.
Perhaps moving the review VMs into the requesting workspace, or applying firewall rules to allow pulling from previous reviews via the SAS URL, although there would need to be a mechanism to list SAS URLS for cancelled / rejected requests.

No source files, tests, or entry points are named. Start by tracing how Airlock requests and review VMs are provisioned and how approved, rejected, and cancelled request data is exposed; define the access boundaries and an on-demand workflow for loading prior requests into the same workspace.
