The network base - experimental
We want to have 1 "main" network for convience.
We want to be able to create networks automatically, once a new
customer is created -> need hooks!
Mapping:
- each network is a "virtual" network. We use vxlan by default, but
could be any technology!
- we need a counter for vxlan mappings / network IDs -> cannot use
Model in etcd:
/v1/networks/
Tests

Creating a network:
1) part of the initialisation / demo data (?)
We should probably provide some demo sets that can easily be used.
