[Impact]
When rendering netplan output from OpenStack network configuration format
(network_data.json), cloud-init would not correctly represent some
bond attributes. The result is that those attributes are not set as
desired.
[Test Case]
The basic idea below is:
a.) launch an instance with proposed version of cloud-init.
b.) inside instance, get cloud-init's network rendering tool from trunk
c.) run the rendering tool against a config that failed before.
d.) check rendered netplan config to verify it has expected bond attributes.
## launch an instance.
$ release=xenial
$ ref=$release-proposed
$ lxc-proposed-snapshot --proposed --publish $release $ref
$ lxc launch $name
$ sleep 10
$ lxc exec $name /bin/bash
## get render tool
% wget https://git.launchpad.net/~cloud-init-dev/cloud-init/plain/tools/net-convert.py -O net-convert.py
% wget https://bugs.launchpad.net/ubuntu/+source/cloud-init/+bug/1690480/+attachment/4887940/+files/network_data.json -O network_data.json
% python3 ./net-convert.py \
--network-data=network_data.json --kind=network_data.json \
--output-kind=netplan \
--mac=eth0,a0:36:9f:2d:93:80 --mac=eth1,a0:36:9f:2d:93:81 \
--directory=out.d
## Now see that the 'mii-monitor-interval', 'mode', and
## 'transmit-hash-policy' are present in output.
% egrep --context=5 '(mii-monitor-interval|mode|transmit-hash-policy)' \
out.d/etc/netplan/50-cloud-init.yaml
bond0:
interfaces:
- eth0
- eth1
parameters:
mii-monitor-interval: 100
mode: 802.3ad
transmit-hash-policy: layer3+4
vlans:
bond0.101:
addresses:

id: 101
[Regression Potential]
Fairly low chance for regression. The bond attributes were just not
being written and now they will be.

Upstream commit at

lxc-proposed-snapshot is
https://git.launchpad.net/~smoser/cloud-init/+git/sru-info/tree/bin/lxc-proposed-snapshot
It publishes an image to lxd with proposed enabled and cloud-init upgraded.
=== End SRU Template ===
Given network-data.json http://paste.ubuntu.com/24561026/
cloud-init generates http://paste.ubuntu.com/24564006/
which is missing
"bond_mode" : "802.3ad",
"bond_miimon" : 100,
"bond_xmit_hash_policy" : "layer3+4"
For the bond specification
As per nplan docs it should be defined as parameters dictionary
https://git.launchpad.net/netplan/tree/doc/netplan.md#n302
mode: 802.3ad
mii-monitor-interval: 100
transmit-hash-policy: layer3+4
In test_configdrive.py it specifies bond_mode as "4", whereas my configdrive specifies it as 802.3ad
