Track kube node reboot status #21

Closed SpComb closed 6 years ago

SpComb commented 6 years ago

Fixes #19

Use a pharos-host-upgrades.kontena.io/reboot annotation timestamp vs the node info BootTime timestamp to track the node reboot state across restarts.

The HostUpgradesReboot condition is updated through the RebootRequired => Rebooting => Rebooted states.

The reboot annotation also guards against spurious restarts during the reboot:
