python-openstackclient currently has a non-zero number of dependencies,
so for admins who would like to run it on laptops or similar it can
get tricky. In opendev, for instance, admins have it installed into
a venv on a jump host, but it's really wonky to keep up with.

Use the opendev/python-builder opendev/python-base pair to make a
minimal image that contains an install of python-openstackclient
and publish it to the osclient org on dockerhub. There is an overall
policy against having binary artifacts such as this appear to be
official deliverables of the OpenStack project, which this is not.
It's also only publishing images based on master, so no warranties
should be implied. But if this makes life easier for a user somewhere,
cool.

This is the first step in reworking the shell argument handling,
clean up and add tests to ensure functionality doesn't change.

* Rework shell tests to break down global options and auth options.
* Make tests table-driven
* Remove 'os_' from 'cacert' and 'default_domain' internal option names

This adds a new option --os-cloud that allows the configuration values
for multiple clouds to be stored in a local file and selected with
a single option.

Internal option names have had 'os_' removed to be comptible with
the options returned from OpenStackConfig().get_one_cloud().

The config file is ~/.config/openstack/clouds.yaml:

Sample

The plugin detection at the top of openstackclient.api.auth did not
detect the plugins at the bottom of that file because, surprise,
they had not been declared yet so the entry points were ignored.

Move both plugin subclasses into openstackclient.api.auth_plugin.

Fix a problem with the password callback that was otherwise made
worse with this change.

When we got picky with the auth arguments we broke using help without
any auth config supplied.  This rearranges things a bit to do the argument
checking when the deferred auth request to Identity occurs so commands
that do not need auth have a chance to live short but useful lives.

If either of OS_USER_DOMAIN_ID or OS_USER_DOMAIN_NAME are present
then we don't tinker with anything. Otherwise, we should set
the USER_DOMAIN_ID to 'OS_DEFAULT_DOMAIN', as this provides a better UX,
since the end user doesn't have to specify these arguments.

Same logic applies for OS_PROJECT_DOMAIN_ID.
