Passes linode_token and other secrets to Ansible through a 0o600 temp
file (@tmpfile) rather than the main --extra-vars JSON blob. Fixes
undefined variable errors for provision tasks that reference linode_token
as an Ansible variable, while keeping secrets out of process listings.
Temp file is removed in finally block regardless of outcome.
Also fixes absolute path for node_chunks_file and other logs-relative
paths so Ansible lookup('file', ...) resolves correctly from any
playbook directory.
