Snapshot create fails using non-ASCII name or description

[Hiroki Tani]

Snapshot create fails using non-ASCII name or descriptions. Creating snapshot stop in status "creating" and "UnicodeDecodeError" is written in cinder/volume.log.

OS: CentOS 7.0
OpenStack version: Liberty (PackStack All in one deployment)
Cinder version: openstack-cinder-7.0.0-1.el7.noarch
Volume backend : scaleio (lvm cause this bug too)

Steps to reproduce:
# cinder snapshot-create --name snapshotα volume
# cinder snapshot-list
+--------------------------------------+--------------------------------------+----------+-----------+------+
| ID | Volume ID | Status | Name | Size |
+--------------------------------------+--------------------------------------+----------+-----------+------+
| fb90cc5c-3c8b-4594-a011-f502fd51b1d1 | 4ce44a3e-a9f9-4ab3-9890-c2ccd6e495d6 | creating | snapshotα | 1 |
+--------------------------------------+--------------------------------------+----------+-----------+------+

Get the following error:

(part of /var/log/cinder/volume.log)

Hello Hiroki, this bug is duplicate of the Bug #1514325 , you can chek it. The issue is with osprofiler/profiler.py which is converting args to string, and python using default encoding as ascii, so the the value passed to cinder-volume should be properly encoded
