Hardcode discovery engine env vars

We've decided it's easier for the local setup of search-api-v2 to pull
in search results from integration whenever search results are needed
for local testing rather than making everyone set up their own personal
discovery engine on gcloud. Therefore the env var values can be
hardcoded rather than being set in the local session.
