added awx collection support for bulk api

return more context for bulk host create

now return list of minimal info about host objects

[
    {
        "name": "lakjdsafoiaweirnladlk",
        "enabled": true,
        "instance_id": "",
        "description": "",
        "variables": "",
        "id": 4593,
        "url": "/api/v2/hosts/4593/",
        "inventory": "/api/v2/inventories/1/"
    }
]

Updated tests, but needed to work around some weird behavior with
sqlite. Apparently it behaves differently around assigning ID's to the
result of bulk_create and that is messed up my use of `reverse` to look
up the url of the hosts
