ACPI is missing on fuel nodes

[Stepan Rogov]

Many customers and peoples are running various Fuel nodes(i.e. controller) as virtual machines.
There are situations when you need to shutdown node gracefully without login on it - ACPI is better solution for it.
It also would be useful on baremetal nodes.

I propose to install acpid service on Fuel nodes(master and slaves) and add it to autostart.

I would say the following - enabled acpid is a problem when someone pushes the button on HW server. I myself prefer to disable it on hw servers in order to not suffer from someone pushing the button accidentally in the data center.

So I would do the following:

1) Introduce a configuration flag to enable acpid
2) Set it to enabled by default for VMs and disabled by default for HW servers
3) Introduce it in the UI and let user decide

Current patchset enables acpid only if /proc/acpi/event exists and node is not a physical one.

    Install and start acpid on virtual nodes

    Some users may be running various nodes (including master node since
    7.0) as virtual machines – acpid allows them to do graceful shutdown or
    reboot without using ssh.

    The commit introduces custom fact to check if ACPI is available via
    procfs on machine. acpid itself is only installed and started if node is
    not physical and has ACPI.
