* HDFS-16586. Purge FsDatasetAsyncDiskService threadgroup; it causes BPServiceActor IllegalThreadStateException 'fatal exception and exit'

Remove the ThreadGroup used by executor factories; they are unused
and ThreadGroups auto-destroy when their Thread-member count goes to zero.
This behavior is incompatible with the configuration we have on the per-volume
executor which is set to let all threads die if no use inside the
keepalive time.

HADOOP-18144: getTrashRoot in ViewFileSystem should return a path in ViewFS.
To get the new behavior, define fs.viewfs.trash.force-inside-mount-point to be true.

If the trash root for path p is in the same mount point as path p,
and one of:
* The mount point isn't at the top of the target fs.
* The resolved path of path is root (eg it is the fallback FS).
* The trash root isn't in user's target fs home directory.
get the corresponding viewFS path for the trash root and return it.
Otherwise, use <mnt>/.Trash/<user>.
