What

Update the jenkins-sync-plugin [1] to support additional Jenkins credentials types required by aerogear digger. The credentials types that we currently create for Android and iOS are CertificateCredential [2] and AppleDeveloperProfileCredential [3]

Why

The jenkins-sync-plugin currently only supports creating 3 types of Jenkins credentials from OpenShift secrets, UsernamePassword, SSH, and Secret File, none of which are used by aerogear digger.
