IonAttestor.signing_key() takes an optional key_id argument
The specified key is returned by looping over the JWK's returned by the read_signing_keys() method on the AttestorKeyManager trait.
Currently the loop matches on the optional key_id field of the JWK struct.
This JWK field is currently not populated when keys are written to file by the trustchain key manager.
Instead, the query key_id should be matched against the compulsory id field associated with each key in the verificationMethod field of the DID Document.
To implement this change, the associated key id's for each key in a DID Document must be maintained in the file system (eg. written to file during the did create operation)
