CLI: Introduce filters on listing containers

[hongbin]

Currently, the server side supports the following filters [1]:

          container_allowed_filters = ['name', 'image', 'project_id', 'user_id',
                                     'memory', 'host', 'task_state', 'status',
                                     'auto_remove']

We'd better to support them in client side. The desired output might look like:

  $ zun list --name xxxx
  $ openstack appcontainer list --image xxx
  ...
