Bug 1216234

Description of problem:
A location can be associated with zero or more realms. The API documentation makes mention of this in the documentation for POST /api/v2/locations and PUT /api/v2/locations/:id, and the UI exposes this capability too. (See the relevant API documentation page at https://sat.example.com/apidoc/v2/locations.html and search for "realm".) However, a GET request to /api/v2/locations/:id will return information about associated realms.

Version-Release number of selected component (if applicable):
Tested against Satellite-6.1.0-RHEL-6-20150424.0 and Satellite-6.1.0-RHEL-7-20150424.0.

How reproducible:
100%

Steps to Reproduce:
1. Issue an HTTP GET request to https://sat.example.com/api/v2/locations/:id
2. Examine the response.
3. Discover that realms are not mentioned.

Actual results:

    [
        u'compute_resources',
        u'config_templates',
        u'created_at',
        u'description',
        u'domains',
        u'environments',
        u'hostgroups',
        u'id',

        u'subnets',
        u'title',
        u'updated_at',
        u'users',
    ]

Expected results:
Same as above, but with realms mentioned.
