Cloned from https://bugzilla.redhat.com/show_bug.cgi?id=1258327
Description of problem:
In very big environments where over 800 Subnets and hundreds of Domains exist it is a very big overhead to be forced to configure Domains & Subnets in the Satellite Server when an IP Address Management system (IPAM) is already in place having all those information.

Version-Release number of selected component (if applicable):
6.1.1

Actual results:
User is forced to configure Domains & Subnets to be able to use Satellite Provisioning

Expected results:
Add the possibilty to specify Domain & Network information freely not having to create/manage hundreds of Domains & Subnets on host creation level.
This would ease the integration of Satellite 6 to other provisioning frameworks where Satellite is only one of several tools being used to provisiong systems.
