Comment 3 for bug 1897818

This updates the Jenkins test to actually use Vault in HA mode without EasyRSA, and works around the status issues in both the Vault and k8s-master charm: https://github.com/charmed-kubernetes/jenkins/pull/641

This fixes the hook error in the k8s-master charm during the Vault restart: https://github.com/juju-solutions/layer-vault-kv/pull/11

This fixes the libjuju unit.resolved() issue (which would be used in the workaround for the hook error in the k8s-master charm): https://github.com/juju/python-libjuju/pull/485

The status issues in the Vault charm were fixed in https://review.opendev.org/c/openstack/charm-vault/+/782585 and https://review.opendev.org/c/openstack/charm-vault/+/782585
