Packer image build will fail to git clone any repos residing inside
internal gitlab. So we define the internal DNS IPs in the network
module while creating the initial infrastructure for packer img builds

To avoid error when there's two images with same name
 use data source to get the latest image to boot up compute nodes

Changing ohpc id and compute node id will trigger it
Will run node registration on ohpc node.

Accessible by calling module.create-ohpc-instance.id
 will return a string

Accessible by calling module.nodes.network
 will return a map which key is node name and its network info

Accessible by calling module.nodes.id
 will return a list of compute node id
Mainly using for null-resource trigger

Modify warewulf config file with compute node info

c0 to compute
