Functional VLAN tagged bonding interfaces are shown as disconnected

[Alexander Litvinov]

After configuring bond and VLAN tagged interfaces on top of it and deploying the server,
VLAN interfaces which are functional, are still shown as disconnected in MAAS UI.

MAAS version: 2.7.1 (8262-g.9a49af7df-0ubuntu1~18.04.1)

Upstream github: https://github.com/canonical-web-and-design/maas-ui/issues/1429

It looks like MAAS may be always creating virtual interfaces in a disconnected state as the link speed is unknown

$ maas $PROFILE machine read $SYSTEM_ID | jq -r '.interface_set | .[] | .name + ": " + (.link_connected|tostring)'
enp1s0: true
enp3s0: true
enp2s0: true
bond0: false
br0: false

MAAS should ensure they are created in a connected state.

I'm thinking they should probably adopt the connected state of the parent (physical device) so that it accurately represents the connection. i.e. if the physical device is disconnected, then the virtual interface would also be disconnected.
