Stage timeouts:
- frontend waits 5s
- web/clsi waits 4s
- clsi-cache waits 3s
This should ensure that the frontend can receive a valid response after
any of the backend requests failed.
The circuit breaker will remain closed for TIMEOUT + jitter of 0-3 times
the TIMEOUT of the respective service. This should avoid the bulk of
traffic to fail and occasionally issue retries without hammering the
instances while down.
Also do not try the next backend when the abort signal has expired.
