The auth_with_unscoped_saml decorator existed to make sure the user
selected the right auth plugin before trying to call either a
'federation domain' or 'federation project' command. This is outdated,
because openstackclient now uses keystoneauth[1] and keystoneauth
removed its entrypoints for the federation plugins[2] since its
_Rescoped class no longer needs them. This patch removes the decorator
since that validation check was the only thing standing in the way of
the commands working correctly. Also removed the '*_list_wrong_auth'
tests since those only existed to test the decorator, and stopped
setting the plugin in the positive tests since the
automatically-determined token plugin should now be fine.

Leverage the new cliff command class attribute (_description)
to get the help of a command, this allows us to mark strings
for translation. We could not do this before since the help
was grabbed from the docstring.

This also depends on a new release of cliff and a bump to the
minimum level in osc's requirements.

When output to shell, the token issue time is fine; however when
selecting the json formatter (via the --format json) option, an
exception is raised when formatting the dataetime data.

Rather than pass in the datetime data, we should format the data
with the ISO 8601 formatting.

Fix argument precedence hack
  Working around issues in os-client-config <= 1.18.0

  This is ugly because the issues in o-c-c 1.19.1 run even deeper
  than in 1.18.0, so we're going to use 1.19.0 get_one_cloud() that
  is known to work for OSC and fix o-c-c with an axe.

Remove return values for set commands
  'identity provider set' and 'service provider set' were still
  returning their show-like data, this is a fail for set commands
  now, don't know how this ever passed before...

Constraints are ready to be used for tox.ini
  Per email[1] from Andreas, we don't need to hack at install_command
  any longer.

Convert to using ClientManager and OpenStackShell from osc-lib.
* Change all internal uses of ClientManager private attributes that are
  now public in osc-lib's ClientManager.  Leave back-compat copies in
  place in OSC's clientManager so we don't break plugins.
* Put some work-arounds in place for changes in osc-lib that we need until
  a new release makes it through the g-r and u-c change process.
* Add a test for Unicode decoding of argv in shell.main() to parallel
  the one in osc-lib.
