The motivation behind this is that HTTP GET /ovirt-engine/api
should not refresh Engine user session, i.e. such request
should not prevent the Engine user session from expiring.

/ovirt-engine/api is not a resource/collection on its own,
it's an entry point to REST interface that lists top-level
resource collections (DCs, VMs, etc.) plus some additional
REST metadata, so it can be considered as "meta resource";
any activity on it should not be considered as activity on
"real" resources. Well, this is my understanding.

Anyway, as far as I understand, the "refresh" flag on queries
was designed to support use case when GUI (client) polls the
Engine for data but still allows user to be auto-logged-out
of GUI due to user's inactivity.
