Context
-------

Using ceph_argparse from within the CephFS driver in OpenStack manila. This command requires passing an argdict specifying the nfs_cluster_id and the export pseudo path. Both the nfs cluster and the export are available and the delete operation can be performed successfully from the CLI

stack@quincy:~/devstack$ sudo ceph --id=manila nfs export rm cephfs /volumes/_nogroup/eb514387-21f2-4a73-adee-cdec4f505056/504dabcd-1e52-4fa4-b40a-e0b24a73720b
Successfully deleted export

Expected result
---------------

We should be able to use ceph_argparse to delete exports of subvolumes

Actual result
-------------

The "ceph nfs export rm <nfs_cluster_id> <pseudo_path>" command issued through ceph_argparse fails with an exception
