Usage: vault step-down [options]

  Force the Vault node to step down from active duty.

  This causes the indicated node to give up active status. Note that while the
  affected node will have a short delay before attempting to grab the lock
  again, if no other node grabs the lock beforehand, it is possible for the
  same node to re-grab the lock and become active again.
