Planner should generate an action plan (AP) that includes steps on when to run-deferred-hooks

[Edin S]

NOTE: I'm currently having to use this tools predecessor, ubuntu_series_upgrade_for_openstack.py because of crasher LP#1962242, so cloud-upgrade-planner might already support my feature request -- but based on a quick grep the feature is unimplemented.

Currently this tool generates an AP that provides instructions to "enable deferred restarts on charms".
e.g.
juju config <charm-name> enable-auto-restarts=False

However, I'd like for this tool to also generate running deferred hooks e.g. after an application has been upgraded, e.g.
      juju set-series rabbitmq-server focal
      # upgrade rabbitmq-server/{0,1,2}
      # ...
      juju upgrade-series 22/lxd/4 complete
      juju run-action --wait rabbitmq-server/2 complete-cluster-series-upgrade
      # FEATURE REQUEST, IMPLEMENT GENERATING THE FOLLOWING OUTPUT
      juju run-action rabbitmq-server/0 run-deferred-hooks --wait
      juju run-action rabbitmq-server/1 run-deferred-hooks --wait
      juju run-action rabbitmq-server/2 run-deferred-hooks --wait
