Add a kosmos-mastodon::dependencies recipe with everything needed to run Mastodon (Node, Ruby, libvips, Elasticsearch, packages) but without the app deployment. The default recipe includes it and only runs the deployment when node['kosmos-mastodon']['deploy'] is true, so a VM can be prepared ahead of a maintenance window.
Stop using the local redisio instance and connect to the external Redis cluster (redis_server role, db 2, password from the credentials data bag) instead. Remove the redisio service dependencies from the systemd units and drop the redisio cookbook dependency.
