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

[kajgm]

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
