DodoApp: Prepare dodo-app to support multiple app repositories

Previously Git repository storing configuration for PCloud
environment, linked dodo-app repositories directly. After this change,
dodo-app will first create config repository which will link
individual application repositories. And PCloud env will link to the
config repo. That way dodo-app manger will be able to create multiple
app repositories per installation.
