Drain

Drain an agent to stop it from accepting new jobs. In-flight jobs continue to completion:

$ osapi client agent drain --hostname web-01

  Hostname: web-01
  Status: Draining
  Message: Agent drain initiated

The agent transitions from Ready to Draining. Once all in-flight jobs finish, the state becomes Cordoned. The agent stays running and continues sending heartbeats -- it just stops pulling new work from the job queue.

Use agent undrain to resume accepting jobs.
