[pmg-devel] [PATCH pmg-api] config: add ips/nets uniquely to the template variables

[Dominik Csapak <d.csapak@proxmox.com>]

otherwise a config with many entries such as:
domain1: ip1
domain2: ip1
domain3: ip1
etc.

unnecessarily adds 'ip1' multiple times to the 'mynetworks' variable

to keep the output sorted (so it's stable) move the sort to the 'join'
