Testing Done: Sanity test + test new bridge format
There are a bunch of open issues with `vlan` interface handling.
Below is the format.

# This should be pretty simple and might not really even need to exist.
|
|
# The key is that we need to call link_create with a type of "dummy"
|
|
# since that will translate to 'ip link add loopbackX type dummy'
|
|
# The config file should probably just indicate that the type is
|
|
# loopback or dummy.
