At the beginning, I would have liked to be able to emit 
"CredentialsAdded" "CredentialsRemoved", to notify ConnMan
that the Cellular service can be published or removed like we do it for 
GSM Contexts.

Now, using "Status" == "registered" property from 
cdma.NetworkRegistration to publish the service into ConnMan might be 
cleaner.

With both solutions, we should handle into oFono the ppp_disconnect 
reason G_AT_PPP_REASON_AUTH_FAIL to try again with other credentials.

Kind regards,
Guillaume
