core: Run tests without data source location retry

Since commit fd6835 the application retries the location of the data
source, this means that some tests will take a long time to run because
the data source is never deployed in the testing environment. To prevent
that this change adds configuration parameters to run those tests with
an alternative configuration that disables the retry.
