Description

http://qa-proxy.ceph.com/teuthology/teuthology-2019-05-02_02:01:02-rbd-master-distro-basic-smithi/3917446/teuthology.log

The "rbd-nbd unmap" command just sends a disconnect request to the "rbd-nbd" process and exits. If this is immediately followed with a "rbd-nbd list-mapped", it might still locate the disconnected process. Therefore, internally delay the "unmap" to give the process time to exit.
