A number of packages were requiring interaction on upgrade even with
do-release-upgrade -f DistUpgradeViewNonInteractive. By setting DPkg
options in apt.conf upgraded packages do the right thing.
Set 'DPkg::options { "--force-confdef"; };' on hosts being upgraded.
Remove all calls to time.sleep and use block_until_unit_wl_status to
manage the timing of the upgrade steps.
Also use run_via_ssh to execute commands while the juju agents are down
during a series upgrade.
Utilities for performing series upgrades.
Place holder for future stand alone series upgrade zaza test.
Small change to overlay template to allow stand alone zaza tests.
Currently interacting with functions in zaza.model requires the
model to be passed in. This has resulted in multiple calls to
get_juju_model(). It is cleaner to push these calls down into
the model wrapper and make the model_name an optional
argument. In addition, the current model name is now cached
without having to check the os.env each time.
Unfortunately this has resulted in the signature changing on a
great many function so this diff is bigger than would normally
be desirable.
