This will allow to trigger profiling of various services that
allow it currently and which APIs support is added to openstackclient.
Cinder and Glance have osprofiler support already, Nova and Keystone
are in progress.
To use this functionality osprofiler (and its storage backend) needs
to be installed in the environment. If so, you will be able to trigger
profiling via the following command, for example:
$ openstack --profile SECRET_KEY user list
At the end of output there will be message with <trace_id>, and
to plot nice HTML graphs the following command should be used:
$ osprofiler trace show <trace_id> --html --out result.html

The similar change to the keystoneclient
