network_ids should be option for basic zones

builder/cloudstack: Make network_ids optional

In Cloudstack basic networking it's not possible to specify network_ids, so remove the
hard requirement on specifying this.

Could you update the commit message to look like this:

@ddoc Could you do a

git commit --amend

and use the message above?

I have the same commit ready in one of my branches so if @ddoc doesn't respond, I'm happy to send it to you.

@petrhosek please do!
