allows to trace various requests through all OpenStack
services that support it. To initiate OpenStack
request tracing `--profile <HMAC_KEY>` option needs to be added to
the CLI command. Configuration and usage details can be found in
[`OSProfiler documentation <https://docs.openstack.org/developer/osprofiler/api.html>`_]
upgrade:
