Allow regular users to specify global credentials password

While the UI is existent the feature simply doesn't work because admin privileges are required for the controller. This adds proper permission checks and also unit tests. To test this: 1. Enable external storage 2. Login as non-admin user 3. Go to personal page and try to change global credentials
