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.

The current identity role list command (both v2 and v3) is
overloaded with listing roles as well as assignments (if you
provide user, group, project or domain options). This is in
addition to the v3 assignment list command designed for this
purpose.

This overloading complicates the fact that roles can now be
domain specific (i.e. have a domain attribute), so the
command 'role list --domain <domain-name' will soon become
ambigious (this is in a follow on patch).

This patch:

- Adds a v2 assignments list, with support for pulling the
user and project from the auth credentials
- For comapability, adds the same auth support to the
existing v3 assignments list
- Deprecates the use of role list and user role list to list
assignments

if there are more than one services be found with one
name, a NoUniqueMatch exception should be raised but
we can see a NotFound Exception raised instead. It is
because in "find_service()", we use "find_resource()"
first, if "find_resource()" return a exception, we just
think it is a NotFound Exception and continue to find
by type but ignore a NoUniqueMatch exception of
"find_resource()". This patch refactor the "find_service()"
method to solve this problem.
