Capabilities class __repr__ still crashes after fix committed

[Rajat Dhasmana]

Initially the AttributeError could be generated via the following steps:

In python console, execute the following

from cinderclient.v2 import capabilities
cap = capabilities.Capabilities(None, {})
print(cap)

The initial patch fixed the issue but the merged patch still throws
error

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/lib/python2.7/dist-packages/cinderclient/v2/capabilities.py", line 25, in __repr__
    if self._info['namespace'] is None:
KeyError: 'namespace'
