Raise import error when repo configs module cannot be imported

[felixwang9817]

Signed-off-by: Felix Wang wangfelix98@gmail.com

What this PR does / why we need it: Previously when the full repo configs module could not be imported, the error was suppressed and the integration tests continued with the default repo configs. This makes it difficult for users who are trying to extend the test suite to realize the issue is an import error.
