Impossible to create cinder volume with unicode metadata when global debug is switched on

[Alexey Stupnikov]

Steps to reproduce:

1. Create env, configure it;
2. Turn on OpenStack debug logging at Logging tab
3. Deploy env
4. Try to create cinder volume with unicode metadata (cinder create --metadata 'test'='тест' 1)

Expected result: volume is created and available
Actual result: volume record in 'creating' state, no actual volume is created.

Reproducibility: 100% with latest cinder updates

Here is a patch that should be applied on both controller and cinder nodes to apply a workaround for this issue. This patch is effectively a workaround to overcome the issue caused by cinder-taskflow integration.

Setting importance to medium as this issue doesn't affect production environments.
