This patch adds support for microversion 3.32 allowing setting and
querying Cinder services' log levels.
Two new commands are available:
cinder service-get-log [--binary {,*,cinder-api,cinder-volume,cinder-scheduler,
cinder-backup}]
[--server SERVER] [--prefix PREFIX]
cinder service-set-log [--binary {,*,cinder-api,cinder-volume,cinder-scheduler,
cinder-backup}]
[--server SERVER] [--prefix PREFIX]
<log-level>
Implements: blueprint dynamic-log-levels
Depends-On: Ia5ef81135044733f1dd3970a116f97457b0371de
