The error is raised if Etcd is configured to use JWT auth tokens and when the user database in Etcd is updated, because the update invalidates all tokens. If retries are requested - try to get a new new token and repeat the request. Repeat it in a loop until request is successfully executed or until `retry_timeout` is exhausted. This is the only way of solving a race condition, because between authentication and executing the request yet another modification of the user database in Etcd might happen. In case if the request doesn't have to be immediately retried - set a flag that the next API request should perform the authentication first and let Patroni to naturally repeat the request on the next heartbeat loop.
