/**
 * Worker and deployment drain operations.

 * Draining is an operator action: it keeps existing in-flight assignments
 * visible while excluding matching workers from new routing decisions. Worker
 * drains apply to one connected worker; deployment drains apply to every
 * current and future worker that registers the same deployment name.
