Title:
  nova-cells doesn't url decode transport_url

Status in OpenStack Compute (Nova):
  New
Status in Messaging API for OpenStack:
  New

Bug description:
  When creating a cell using the nova-manage cell create command, the
  transport_url generated in the database is url-encoded (i.e. '=' is
  changed to '%3D', etc.)  That's propably the correct behavior, since
  the connection string is stored as URL.

  However, nova-cells doesn't properly decode that string.  So for
  transport_url credentials that contain url-encodable characters, nova-
  cells uses the url encoded string, rather than the actual correct
  credentials.

  Steps to reproduce:

  - Create a cell using nova-manage with credentials containing url-
  encodable characters:

  nova-manage cell create  --name=cell_02 --cell_type=child
  --username='the=user' --password='the=password' --hostname='hostname'
  --port=5672 --virtual_host=/ --woffset=1 --wscale=1

  - nova.cells table now contains a url-encoded transport_url:

  mysql> select * from cells \G
  *************************** 1. row ***************************
     created_at: 2014-12-30 17:30:41
     updated_at: NULL
     deleted_at: NULL
             id: 3
        api_url: NULL
  weight_offset: 1
   weight_scale: 1
           name: cell_02
      is_parent: 0
        deleted: 0
  transport_url: rabbit://the%3Duser:the%3Dpassword@hostname:5672//
  1 row in set (0.00 sec)

  - nova-cells uses the literal credentials 'the%3Duser' and
  'the%3Dpassword' to connect to RMQ, rather than the correct 'the=user'
  and 'the=password' credentials.
