This follows the implementation in Apache Cassandra. The auth tasks executed by delay_until_system_ready() usually perform a query with QUORUM consistency level, which can fail if some nodes are unavailable. So, we provide both exception handling and a retry mechanism. Fixes #3038 Signed-off-by: Duarte Nunes <duarte@scylladb.com>
