1. When we decommission some BEs with SSD disks, if there are no SSD disks on the remaining BEs, it will be impossible to select a suitable destination path. In this case, we need to ignore the storage medium property and try to select the destination path again. Set `isSupplement` to true will ignore the storage medium property. 2. When the BE nodes where all replicas of a tablet are located are decommission, and this task is a VERSION_INCOMPLETE task. This will lead to failure to select a suitable dest replica. At this time, we should try to convert this task to a REPLICA_MISSING task, and schedule it again.
