`nonce` is an opaque random string used to lookup verification requests. URL-safe.
Example: "UPBQ3JE2DGJYHP5CPSCRIGTHRTCYXMQPNQ"
`expected_credentials` is a JSON list of credential types that must be present in this VP.
Example: ["FinancialSituationCredential", "HomeConnectivitySurveyCredential"]
`expected_contents` is a JSON object that places optional constraints on the contents of the
returned VP.
Example: [{"FinancialSituationCredential": {"financial_vulnerability_score": "7"}}]
`action` is (for now) a JSON object describing the next steps to take if this verification
is successful. For example "send mail to <destination> with <subject> and <body>"
Example: {"action": "send_mail", "params": {"to": "orders@somconnexio.coop", "subject": "New client", "body": ...}
`response` is a URL that the user's wallet will redirect the user to.
`submitted_on` is used (by a cronjob) to purge old entries that didn't complete verification
