Policy documentation wrong for os-show_image_metadata endpoint

[Felipe Monteiro]

The policy documentation for os-show_image_metadata endpoint is inconsistent with the implementation.

In policy documentation, the endpoint is listed as enforcing "volume_extension:volume_image_metadata": https://github.com/openstack/cinder/blob/9fbf236dc17d67404e2ce9ced517182716d72e6f/cinder/policies/volume_metadata.py#L102

But in the code it is clear that no policy enforcement is performed: https://github.com/openstack/cinder/blob/0cf910d4345c000e8c306b1cb2b2dd291975cf71/cinder/api/contrib/volume_image_metadata.py#L123

    Fix policy documentation for os-show_image_metadata endpoint

    The policy documentation for os-show_image_metadata endpoint
    is inconsistent with the implementation.

    In policy documentation, the endpoint is listed as enforcing
    "volume_extension:volume_image_metadata": [0]

    But in the code it is clear that no policy enforcement is performed: [1]

    This PS removes the os-show_image_metadata entry from the policy
    documentation for consistency.
