[CE-374] Ansible plays updating/redeploying BNA archive

This patch adds onto the ansible agent plays. Specifically, it adds
upgradecomposer.yml, which invokes roles/upgrade_compose/plays.yml,
which invokes roles/upgrade_compose/composerupgrade/tasks/apply.yml
on the builder node. This uploads the bna in the secrets/networks
folder to the builder node then runs 'composer update' with the bna.
