Cloned from https://bugzilla.redhat.com/show_bug.cgi?id=1216236
Description of problem:
The API returns significantly different information for the following two calls:

• POST /api/v2/locations
• GET /api/v2/locations/:id

This is problematic for two reasons:

• This is inconsistent with how other paths behave, which makes writing client code harder to do.
• Getting authoritative information about a just-created location requires a follow-up API call, which is time-consuming.

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:
Here's a sample script:

>>> from nailgun import entities
    >>> loc_attrs = entities.Location().create_json()
    >>> loc_attrs2 = entities.Location(id=loc_attrs['id']).read_json()
    >>> loc_attrs.keys()  # contents of response to POST call
    [
        u'ancestry',
        u'apply_info_task_id',
        u'created_at',
        u'default_info',
        u'description',
        u'id',
        u'ignore_types',
        u'katello_default',
        u'label',
        u'name',
        u'title',
        u'updated_at',
    ]
    >>> loc_attrs2.keys()  # contents of response to GET call
    [
        u'compute_resources',
        u'config_templates',
        u'created_at',
        u'description',
        u'domains',
        u'environments',
        u'hostgroups',
        u'id',
        u'media',
        u'name',
        u'organizations',
        u'parameters',
        u'select_all_types',
        u'smart_proxies',
        u'subnets',
        u'title',
        u'updated_at',
        u'users',
    ]

Actual results:
The actual results are as shown in the above example.
