when a certificate is near expiration (configurable by `SECRET_GRACE_PERIOD_RATIO`, defaulting to half of the expiration). If the SDS server
is still interested in this certificate (ie, Envoy is still connected and requesting the certificate), the SDS server will send another request
to generate a new secret and push the updated certificate to Envoy. This ensures that we do not permanently watch certificates even after
