Cinder client does not support Cyrillic names of Cinder volumes

[Anatolii Neliubin]

Detailed bug description:
 Cinder CLI client does not support Cyrillic symbols in the names of Cinder volumes
Steps to reproduce:
 Install the simplest configuration: controller, compute+cinder
 Create the volume with Cyrillic symbols in --display-name
  #cinder create 1 --display-name 'тест'
 get the information about the volume with --debug option:
  # cinder --debug show d232229d-f732-4d83-b7e0-da45b4f864ba
The name field in the output is not shown properly: "name": "\u0442\u0435\u0441\u0442"
# echo $LANG
en_US.UTF-8

Expected results:
 Cinder client should work correctly with any unicode text
Workaround:
 Not to use any Cyrillic symbols
Description of the environment:
  MOS 9.2
  cinder CLI - 1.11.0

Just want to note that 1664958 is about Cinder service itself, but this ticket is about cinder client. We can join this but with 1664958, but I think we need to mention about the behavior of Cinder CLI with --debug option.
