deploy.sh: Wrapper for deployment scripts

The `deploy.sh` script ensures the execution environment is correct by
configuring the Ansible Vault secret, unlocking the `rbw` vault, and
requesting an SSH client certificate.  It then runs the specified
end-to-end deployment script from the `deploy` directory.
