Bug description:
  === Begin SRU Template ===
  [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:
              - 104.130.20.119/24
              id: 101

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

  [Other Info]
  Upstream commit at
    https://git.launchpad.net/cloud-init/commit/?id=910ed46124e

  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
