Subject: ceph_volume_client: Fix failure of test_idempotency
X-Git-Tag: v15.2.10~20^2~3
X-Git-Url: http://git-server-git.apps.pok.os.sepia.ceph.com/?a=commitdiff_plain;h=a20b7790fea4a42b6abae34cc81ef27d32e7b0aa;p=ceph.git

ceph_volume_client: Fix failure of test_idempotency

With the test environment, 'args must be encodeable
 as a bytearray' error is seen for 'ceph_mds_command'.
Hence removed tuple and passed the JSON formatted string.

Fixes: https://tracker.ceph.com/issues/48830

(cherry picked from commit 1c6c172a9b665d6b769d67e301061dbd7b044472)
