Dean Troyer 6a15f90dae osc-lib: shell
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.
