[train] Ensure get_requests_for_local_unit doesn't fail on incomplete relation
This is a rebuild/make sync for charms to pickup the fix in charmhelpers to fix
any inadvertant accesses of ['ca'] in the relation data before it is available
from vault in the certificates relation. Fix in charmhelpers is in [1].
Tox 4.0.0 was recently released and it has several breaking changes.
We pin to < 4.0.0 here. We are planning to move forward only on the
master charm branches.
Tox is also pinned to < 4.0.0 for stable branches in upstream
openstack-zuul-jobs as well as in zosci-config. However, the
requires= section in the charm's tox.ini file ends up installing
tox>4, wiping out the zuul-pinned tox<4 that was already installed
installed. This patch fixes that.
This is the main patch for the migration of the stable/21.10
charm to charmhub for the stable/train branch (train track on
charmhub). This patch initially supports bionic from queens
to train, and does not support ussuri. It supports upgrades
from bionic-queens to bionic-train (with each intermediate
step needed). Crucially it does NOT set a default
openstack-origin, which means installing train/stable
without specifying the openstack-origin will result in a
bionic-queens installation. This is intentional as the branch
covers queens to train.
* use stable/21.10 libraries
* use zaza/zaza-openstack-tests at stable/21.10
* build.lock files for reactive charms
* bundles refer to ~openstack-charms candidate channel
