Test cell names inconsistent with variable names

Low Severity

The rename changed variable names from eu_region/us_region to us1_cell/us2_cell and updated the hostnames accordingly (i.am.us1..., i.am.us2...), but the Cell constructor name arguments were left as "eu" and "us". So us1_cell is a Cell named "eu" with a us1 hostname, creating confusing test data that could mislead future developers.
