Backup and DR Service hotfixes hf-11.0.12.3217, hf-11.0.12.3218, and hf-11.0.12.3219 automatically update backup/recovery appliances

## Announcement Backup and DR Service hotfixes `hf-11.0.12.3217`, `hf-11.0.12.3218`, and `hf-11.0.12.3219` automatically update backup/recovery appliances. These hotfixes address the following issues: * Oracle DB application backups wait indefinitely for in-progress log backups to complete. These log backups, in turn, cannot obtain a lock mutex to discover the backup staging LUNs, resulting in an indefinite hang. This issue occurs when the size of the application transaction logs exceeds the log backup staging size. * Cloud stats are repeatedly logged into the enginemgr log and increase log usage.
