Testing with revoked and not-revoked credential

[BigBlueHat]

Test configuration per implementation should provide:

• a revoked credential
• a credential not currently revoked

Each credential will be checked for structural compliance and the referenced credentialStatus's statusListCredential endpoint will be used to retrieve the BitstringStatusListCredential containing the credentials status.
