Guide misses SSL configuration and point to a script that by default use plain-text

[Luiz Otavio de Oliveira]

- [ ] This doc is inaccurate in this way: ______
- [ ] This is a doc addition request.
- [x] I have a fix to the document that I can paste below including example: input and output.

In the Configure Openstack section the guide suggests a script that doesn't work in the environment configured following the guide.

line 12 in 'openrc' script sets OS_AUTH_URL env to 'http' (plain-text) when there is no 'OS_AUTH_PROTOCOL' env set (what is the case here), causing subsequent 'openstack endpoint list' to fail.

When you add keystone:certificates relation to the vault:certificates, the keystone charm updates the configuration to require SSL.

I suggest to set 'OS_AUTH_PROTOCOL=https' env and instruct how to download vault CA cert and set 'OS_CACERT' env pointing to it.
