.A retry mechanism is introduced in the `radosgw-admin sync status` command Previously, when the multisite sync sent requests to a remote zone, it used a round robin strategy to choose one of its zone endpoints. If that endpoint was not available, the http client logic used by the `radosgw-admin sync status` command would not provide a retry mechanism, and thus report input/output error. With this enhancement, a retry mechanism is introduced in the sync status command by virtue of which, if the chosen endpoint is unavailable, a different endpoint is selected to serve the request.
