@short An abstract base class to sign keys asynchronously
To use a SignKeyJob, first obtain an instance from the
CryptoBackend implementation, connect the progress() and result()
signals to suitable slots and then start the job with a call
to start(). This call might fail, in which case the ChangeExpiryJob
instance will have scheduled it's own destruction with a call to
QObject::deleteLater().
After result() is emitted, the SignKeyJob will schedule it's own
destruction by calling QObject::deleteLater().
