DPF: Fix Azure storage copy process

[algattik]

What this PR changes/adds

Fixes end-to-end azure storage copy process, and adds a system test to verify it.

The EDC provides the DPF with a storage access signature (rather than storage account key) for the sink. The storage access signature is passed via key vault.

In a separate PR we will provide a design decision record to document the process.

Why it does that
