SSI-Streetcred: Account Deactivation

[FarrandTom]

Context: If a user no longer wants to use Opus and wishes to deactivate their account there needs to be a user flow to allow them to do this.

On the SSI-Streetcred side this is represented as a revokation of the Proof of Account Ownership verifiable credential (VC) held within their wallet.

Issue: Currently there is no functionality to support revokation of Proof of Account Ownership VCs.

Next steps: Familiarise yourself with Streetcred. These reference points may be useful for working with credential revokation: One and two.

Implementation of the desired user flow:

1. User selects account deactivation in the Opus front end.
2. They are removed from the User database in the Opus server.
3. This triggers the revokation of the Proof of Account Ownership VC from their personal wallet.
