Shutdown -r now halted VM

[rgruyters]

RancherOS Version: (ros os version)
version 1.1.0

Where are you running RancherOS? (docker-machine, AWS, GCE, baremetal, etc.)
ESX 5.5 (vSphere)

When you do a sudo shutdown -r now it halts the VM rather than a reboot.

the shutdown command is a really incomplete thing - I think it just ignores the -r

I can confirm the same problem. As a workaround, sudo reboot works fine.

Looking into this as part of #2121. Args are being ignored for sure, but it's specifically when the shutdown container is launched. Right now runDocker is not deriving its command arguments correctly, I have a fix which I will put in my PR as well.

You can see the specfiic power command go from LINUX_REBOOT_CMD_RESTART to LINUX_REBOOT_CMD_POWER_OFF in the extra log bits I put in below.

Reproduced on v1.1.3 (VMware ESXi guest):
sudo shutdown -r now has inconsistent behaviour and results in machine powered off state instead of reboot 2 out of 5 times).

Tested with Rancheros v1.2.0-rc2.
Now we can restart rancheros using shutdown -r now.
