Subject: After downloading provider.json successfully, ConfigurationWizard now
 can download eip-service.json and ca.crt without having the latter as a
 predefined trusted certificate. It does not ask anything about trusting the
 new certificate as far as selecting a custom provider means that the user
 trusts that url.

Next step: make provider.json also downloadable from https address using
ca.cert not trusted.
