server_action not running reboot

[Darren Wang]

When running action `reboot_soft` or `reboot_hard`, it always outputs ok, after checking how the module works, I found status checking logic for actions contradicts to openstack compute api.

In the compute API, soft reboot is only available when instance status is `ACTIVE`, but in the ansible module, if the instance status is `ACTIVE` for action `reboot_soft` when checking `_action_map`, the module will exit without changes before executing actions.
