A new Galera feature that allows retrying of applying of writesets at slave nodes (codership/mysql-wsrep-bugs/#1619). Currently replication applying stops for first non ignored failure occurring in event applying, and node will do emergency abort (or start inconsistency voting). Some failures, however, can be concurrency related, and applying may succeed if the operation is tried at later time. This feature introduces a new dynamic global option variable "wsrep_applier_retry_count" that controls the retry-applying feature: a zero value disables retrying and a positive value sets the maximum number of retry attempts. The default value for this option is zero, which means that this feature is disabled by default. Signed-off-by: Julius Goryavsky <julius.goryavsky@mariadb.com>
