> In the install wizard, after host registration, we need to know the number of hosts running each possible operating system.
> *Example request:*
> {code:java}
>  GET
> http://localhost:8080/api/v1/hosts?format=summary
> {code}
> Example response:
> {code:java}
> {    "operating_systems": [        "redhat6": 75,        "debian7": 100
>     ]
> }
> {code}
> Note that if there are zero hosts for an operating system type, then it is not included in the array.
> This structure allows us to add additional summary information as siblings to "operating_systems" in the future.
