Develop to staging (#117)

* updating loopback 4 * pinning mongo version * removing comment from .env line which was breaking the import * removing comment that is breaking env example * making scripts use diff connection strings per instance * simplifying data import * making gateway wait for other services * fixes #83; lb cannot be found due to blockchain subdomain hack * New altruist implementation (#100) * new altruist implementation * adding check for blank relaypath, not just undefined * Updating example to match realities * pushing feature branch to staging * fixing bad subdomain parsing * removing subdomain hack, localhost can work with subdomains * db test for staging * db test for staging * db test for staging * db test for staging * fixing logging of debug and wrapping axios in try catch * testing on usw2 * fixing memory reservation for fargate * removing excess logging, vestigal interfaces * restoring CORS headers * restoring CORS headers * restoring CORS headers * restoring CORS headers * restoring CORS headers * restoring push on master to production files * updating requires to imports, resolving PR comments * reverting logger import change * pushing to usw2 * pointing workflows back to correct branches * Update task for e2 * feat: add local setup of relations in timescaledb * Adding back missing allowed headers (#112) * new altruist implementation * adding check for blank relaypath, not just undefined * Updating example to match realities * pushing feature branch to staging * fixing bad subdomain parsing * removing subdomain hack, localhost can work with subdomains * db test for staging * db test for staging * db test for staging * db test for staging * fixing logging of debug and wrapping axios in try catch * testing on usw2 * fixing memory reservation for fargate * removing excess logging, vestigal interfaces * restoring CORS headers * restoring CORS headers * restoring CORS headers * restoring CORS headers * restoring CORS headers * restoring push on master to production files * updating requires to imports, resolving PR comments * reverting logger import change * pushing to usw2 * pointing workflows back to correct branches * adding back origin,ua headers * fixes #108; uses altruist system as backup for sync check * removing leftover cache breaker and changing it to 30 second redis cache for failure sessions Co-authored-by: Roniel Valdez <[email protected]>
