With the introduction of the DFW3 region, there are new projects
consistent across all regions. We want to switch to using those, but
right now our existing resources are in a legacy project that only
exists in the SJC3 region. Add the new projects to our bridge config
for both regions as new clouds, and remove the nonfunctional DFW3
from the old one for clarity. Once we've built up new resources and
cleaned up the old project in SJC3, we can clean up the entries
associated with it.
