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.
