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.

We're trying to change cliff for the better, by improving the UX
of the help command. But cliff tests against the tip of OSC.

Temporarily skip the tests that are failing and then update them
once the fix for cliff has been merged.

The patch in question: https://review.openstack.org/#/c/201258/

User should be able to specify the endpoint type through
a CLI optional argument/ENV variable setting. We will name this new
optional argument: --os-endpoint-type (Env: OS_ENDPOINT_TYPE) and
based on the value given, the service API will use that specific
endpoint type. Possible values: public, admin, internal.
