API & CLI to reboot a host immediately when setting a configuration

[ggiamarchi]

A common use case with PXE Pilot is to deploy a configuration for a host that launch an operating system installer. Most of the time, when doing that we want to reboot the machine immediately. Currently, those two steps can't be done with a single command. Using the CLI, we have to run

pxe-pilot config deploy CONFIG HOST

and then,

pxe-pilot host reboot HOST

It would be great to do it in one line using the option --now or --reboot on config deploy command

pxe-pilot config deploy --now CONFIG HOST
