A state machine for osd destroy phase of osd-replacement flow. The state machine is implemented in OSD health goroutine, where each step is handled on a separate tick. State machine is responsible for draining, destroying OSD, and reserving its CRUSH position, downscalling its deployment, and adding "readyForSwap" annotation. Destroy phase does not zap the device on purpose. On disk signature is kept to avoid automatic reprovisioning of destroyed OSD and to detect physical swap.
