SSL: workaround for session timeout handling with TLSv1.3. OpenSSL with TLSv1.3 updates the session creation time on session resumption and keeps the session timeout unmodified, making it possible to maintain the session forever, bypassing client certificate expiration and revocation. To make sure session timeouts are actually used, we now update the session creation time and reduce the session timeout accordingly. BoringSSL with TLSv1.3 ignores configured session timeouts and uses a hardcoded timeout instead, 7 days. So we update session timeout to the configured value as soon as a session is created.
