[BUG] mysql orc errors

[xuriwuyun]

Describe the bug
Issues encountered during MySQL ORC mode testing:

• The primary node frequently restarts, and the replica may encounter IO thread anomalies: "could not find next log; the first event '' at 4, the last event read from '/var/lib/mysql/binlog/example-mysql-cluster-mysql-0-bin.000002' at 197," while the primary node does not have the 000002 file.

• After multiple master-slave switches, a multi-master situation may arise where they are synchronizing with each other.

• The MasterFailoverLostInstancesDowntimeMinutes configuration marks nodes as being in a "downtimed" state for ten minutes after an anomaly occurs. However, if pods are deleted during this period, various abnormal conditions may occur.

• The replica node is not detected by ORC, resulting in failures in executing failover and switchover operations.
