> Currently some customer has users accounts that are functional ids (fid) to manage application
and application data under the path /data/FID. These fid's also get a home directory under
/user path. The user's home directories are limited with space quota 60 G. When these fids
delete data, due to customer deletion policy they are placed in /user/<FID>/.Trash location
and run over quota.
> For now they are increasing quotas for these functional users, but considering growing
applications they would like the .Trash location to be configurable or something like  /trash/\{userid}
that is owned by the user.
> What should the configurable path look like to make this happen? For example, some thoughts
may relate whether we want to configure it for per user or per cluster, etc.
> Here is current behavior:
> fs.TrashPolicyDefault: Moved: 'hdfs://ns1/user/hdfs/test/1.txt to trash at: hdfs://ns1/user/hdfs/.Trash/Current/user/hdfs/test/1.txt
> for path under encryption zone:
> fs.TrashPolicyDefault: Moved: 'hdfs://ns1/scale/2.txt' to trash at hdfs://ns1/scale/.Trash/hdfs/Current/scale/2.txt
