open-vault/command/step-down.go
Jeff Mitchell 11ddd2290b Provide 'sys/step-down' and 'vault step-down'
This endpoint causes the node it's hit to step down from active duty.
It's a noop if the node isn't active or not running in HA mode. The node
will wait one second before attempting to reacquire the lock, to give
other nodes a chance to grab it.

Fixes #1093

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.
