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
(https://review.openstack.org/#/c/255308/) was abandoned as new
CLI extenstions are not more accepted to python-keystoneclient.

Nothing too complicated here.  I fixed a bunch of spacing issues
that I saw in OSC.

Adjusted conditional statements to use instanceof when
comparing variables. Instanceof supports inheritance type
checking better than type.

OCC now requires all regions to be listed in the cloud
configuration. Update the shell unit tests to list all
of the regions being tested.

Configuration of logging gets triggered twice.  The first time it
uses the CLI options when the application is started and second
it uses the configuration file after that is read.  The state of
the logging needs to be saved from the first to the second time,
so I created a class.

This will allow users to record logs of all their commands into
a predefined log file, in clouds.yaml. The log should have a
format similar to that of oslo.log.

Setting default versions in parsed args makes it so OCC
cannot tell if the argument was parsed, an environment
variable was set or it is just defaulted.  In order to
set api versions from OCC, it will have to be defaulted
after processing OCC.
