wrong name for eu region

[sailingd]

I believe you have the incorrect region name defined in common/regions.py for "eu". I think that is supposed to be "europe" (to get translated to utilizing https://europe-backstory.googleapis.com as the base URL)

Thank you for catching this @sailingd. We "fixed" it for the new v1alpha APIs, where "eu" is required, but it looks like we broke the Backstory API. I've submitted this change to support both: https://github.com/chronicle/api-samples-python/pull/166

In the meantime, you might make that same change to common/regions.py to work around the issue.

Thanks again! @dandye
