OpenStack Post-Deployment Info/Actions should be re-ordered

The current output at the end of deploying OpenStack is as follows:

```
Post-Deployment Info/Actions:

[common]
- run ./configure to initialise your deployment
- source novarc
- add rules to default security group: ./tools/sec_groups.sh
- run ./tools/vault-unseal-and-authorise.sh
```

The ordering however should have the user run the `vault-unseal-and-authorise.sh` script first, otherwise the prior steps will fail. The ordering should look like:

```
Post-Deployment Info/Actions:

[common]
- run ./tools/vault-unseal-and-authorise.sh
- run ./configure to initialise your deployment
- source novarc
- add rules to default security group: ./tools/sec_groups.sh
```

Find where the “Post-Deployment Info/Actions” block is assembled and inspect the listed ./tools/vault-unseal-and-authorise.sh, ./configure, novarc, and ./tools/sec_groups.sh entries. Reorder the displayed actions so vault unsealing comes first, then verify that the generated output matches the requested order.
