This is a second attempt of #3:
We want our ConfigSource to read configurations from sources with lower ordinals. MP Config does not support this yet (see eclipse/microprofile-config#470), but Smallrye Config makes this possible via ConfigSourceFactories.
@infeo used this approach already, but due to problems with non-singleton config instances (one per class loader), we decided to use a less complex (but also less capable) approach.
Now the situation changed, as being able to read existing configs is nonnegotiable for proper unit tests.
