salt: salt doesn't support LXC 3.0+

Description of Issue/Question

Creation of LXC with network_profile with LXC 3.0+ results to unusable containers.

The problem is that salt doesn’t support the new config keys supporting nic settings:

lxc.net.[i].type
lxc.net.[i].flags 
lxc.net.[i].link 
lxc.net.[i].mtu 
lxc.net.[i].name 
lxc.net.[i].hwaddr 
lxc.net.[i].ipv4.address 
lxc.net.[i].ipv4.gateway 
lxc.net.[i].ipv6.address 
lxc.net.[i].ipv6.gateway 
lxc.net.[i].script.up 
lxc.net.[i].script.down

Setup

salt/lxc.sls

create-lxc-foo:
  lxc.present:
    - name:  foo
    - profile: ubuntu1804
    - network_profile: foo_network

pillar/profile.sls

lxc.container_profile:
  ubuntu1804:
    template: download
    options:
      dist: ubuntu
      release: bionic
      arch: amd64

pillar/network.sls

lxc.network_profile:
  foo_network:
    eth1:
      link: lxcbr0
      type: veth
      flags: up

After reading lxc module in 2018.3.3 and develop branches, I see that module only supports old keys.

@adam-codeberg: since you are working on the modules/lxc.py, here is a “quick fix” I personnaly had to do: https://github.com/saltstack/salt/issues/52219#issuecomment-535421741

as temporary workaround you can set empty network profile:

lxc.network_profile:
  default:
    eth0:
      disable: true

and use /etc/lxc/default.conf as network configurator
