Configure OpenStack in charm-deployment-guide

This bug tracker is for errors with the documentation, use the following as a template and remove or add fields as you see fit. Convert [ ] into [x] to check boxes:

- [X] This doc is inaccurate in this way:
Using juju version 3.1.5-genericlinux-amd64 the following set of commands do not work:

juju run -m openstack --unit vault/leader 'leader-get root-ca'
juju run -m openstack --unit keystone/leader 'leader-get admin_passwd'

- [X] This is a doc addition request.
- [X] I have a fix to the document that I can paste below including example: input and output.

the updated charm and juju require the commands to be modified

juju run -m openstack vault/leader get-root-ca
juju exec openstack --unit keystone/leader leader-get admin_passwd

The code for the sources ~/openstack-bundles/stable/openstack-base needs to be changed as well.

the openrc:
if [ ! -z $JUJU_MODEL ]; then
  _juju_model_arg="-m $JUJU_MODEL"
fi
_keystone_major_version=$(juju status $_juju_model_arg keystone --format yaml| \
    awk '/^ version:/ {print $2; exit}' | cut -f1 -d\.)

openstack --version 2>&1 > /dev/null || true

if [ -d ~/snap/openstackclients/common/ ]; then
  # When using the openstackclients confined snap the certificate has to be
  # placed in a location reachable by the clients in the snap.
  _root_ca=~/snap/openstackclients/common/${JUJU_MODEL-""}root-ca.crt

  _root_ca=/tmp/${JUJU_MODEL-""}root-ca.crt
fi
juju run $_juju_model_arg vault/leader get-root-ca | tee $_root_ca >/dev/null 2>&1

if [ $_keystone_major_version -ge 13 -o \

The openrcv3_project:
_OS_PARAMS=$(env | awk 'BEGIN {FS="="} /^OS_/ {print $1;}' | paste -sd ' ')

    _keystone_ip=$(juju run $_juju_model_arg keystone/leader -- 'network-get --bind-address public')
fi
_password=$(juju $_juju_model_arg exec --unit keystone/leader leader-get admin_passwd)

if [ ! -z "$_root_ca" -a -s "$_root_ca" ]; then
