MDEV-27862 Galera should replicate nextval()-related changes in sequences with INCREMENT <> 0, at least NOCACHE ones with engine=InnoDB
Sequence storage engine is not transactionl so cache will be written in stmt_cache that is not replicated in cluster. To fix this replicate what is available in both trans_cache and stmt_cache. Sequences will only work when NOCACHE keyword is used when sequnce is created. If WSREP is enabled and we don't have this keyword report error indicting that sequence will not work correctly in cluster. When binlog is enabled statement cache will be cleared in transaction before COMMIT so cache generated from sequence will not be replicated. We need to keep cache until replication. Tests are re-recorded because of replication changes that were introducted with this PR. Reviewed-by: Jan Lindström <jan.lindstrom@mariadb.com>
