Warn when default credentials are being used

Description

Using default credentials in production is bad and users should never do
that but we have seen that again and again over time. This patch will
cause Opencast to print a big warning if the passwords are not changed.
Everything will run as usual (important for testing) but it's now more
likely that users will notice they have a problem.
