[CELEBORN-960] Exclude workers without healthy disks
### What changes were proposed in this pull request?
The master checks the number of healthy disks in the woker and decides
whether to exclude it.
### Why are the changes needed?
When the disks of all the workers are unhealthy, HDFS is not enabled, and
the master does not exclude the workers, the spark client calls
checkWorkersAvailable and returns available, and the shuffle write ultimately
fails without fallback.
