configuration: use "fake" values for tests

These tests don't validate if options are valid for the storage-driver,
nor do they test if the storage-driver itself is valid. However, the tests
were using actual values (such as s3) and options (such as "region") which
may lead to the conclusion that it's also testing validity of those values.

This patch replaces the test-values with non-existing driver-names and
options to make it more clear these are fake values.
