All APIs for GET collections return in response proper json obects:

http://10.35.64.2:3000/architectures?format=json {"architecture":{"name":"x86_64","id":1}},{"architecture":{"name":"i386","id":2}}]

But 'hosts' API returns only a list of host names and no hosts properties:

http://10.35.64.2:3000/hosts?format=json
["itzik1.qa.lab.tlv.redhat.com","test.qa.lab.tlv.redhat.com","testLena.qa.lab.tlv.redhat.com"]
