The credentials_required signal is emitted when the source requires credentials to connect to
(possibly remote) data store.
The credentials can be passed to the source using invoke_authenticate
function. The signal is emitted in the thread-default main context from the time the registry was created.
Note: This is just a proxy signal for the ESource::credentials-required signal.
