This parameter must be available in nailgun - there is code in nailgun and
UI which relies on this parameter.

This parameter can be set to other values when used for fake UI and
functional tests for UI and fuelclient.

> 3) *release *- It is the number of Fuel release. Frankly, don't need this

It is shown on UI.

> 4) *openstack_version *- It is just an extraction from openstack.yaml [2].
> 5) *api *- It is 1.0 currently. And we still don't have other versions of
> API. Frankly, it contradicts to the common practice to make several
> different versions available at the same time. And a user should be able to
> ask API which versions are currently available.

> 7) *X_sha* - This does not even require any explanation. It should be rpm
> -qa instead.
