Simplify usage of pre-remove role (#8334)
- Use builtin task scheduling of ansible (same task on each host)
  instead of manual looping on master

Benefits:
- One less play in remove-node.yml playbook
- Parralel node drain
- Drain parameters (timeout, grace period, retries,
  allow_ungraceful_removal) can be adjusted separately for each node
  with ansible variables
