[Starlingx-discuss] [DOCS] New location of Ansible bootstrap playbook (bootstrap.yml)

Hi, My following commit is merged today. It restructures StarlingX ansible-playbooks repo. https://opendev.org/starlingx/ansible-playbooks/commit/6e6e564a4f5a92020f822... As a result, the deployment/installation guild (e.g. for AIO-SX https://docs.starlingx.io/deploy_install_guides/current/bare_metal_aio_simpl...) needs to be updated to address the new location of bootstrap playbook. The path for the bootstrap playbook (bootstrap.yml) is changed from /usr/share/ansible/stx-ansible/playbooks/bootstrap/bootstrap.yml to /usr/share/ansible/stx-ansible/playbooks/bootstrap.yml. Thanks, -Wei
