Cheng Chang ee50b8d499 Be able to decrease background thread's CPU priority when creating database backup (#6602) ... Summary: When creating a database backup, the background threads will not only consume IO resources by copying files, but also consuming CPU such as by computing checksums. During peak times, the CPU consumption by the background threads might affect online queries. This PR makes it possible to decrease CPU priority of these threads when creating a new backup.
