Description

The trash emptier only runs in the NN yet deletes files via the client (and therefore makes self IPCs), let's modify it to remove files directly. This could be handled as part of moving trash server side (HADOOP-8598) or simply by creating a new trash policy (since the emptier lives in the default trash policy) and configuring the NN to use it by default.
