In modern distributions /proc/acpi/event is deprecated, so puppet will not apply in host.pp acpi support

[Alexandr Kostrikov]

Ubuntu 14.04 and Centos 7 does not have /proc/acpi/event because it is deprecated
https://bugzilla.redhat.com/show_bug.cgi?id=613315

But we have in https://github.com/openstack/fuel-library/blob/master/deployment/puppet/nailgun/manifests/host.pp#L130 check for acpi_event.

That could lead to situation when virtual machine supports acpi, but does not install acpid.

This is basically a tech debt – we should introduce a custom fact with list of CPU flags (from /proc/cpuinfo), and determine this way if ACPI is available.

    Check the acpid version before starting the service

    acpid 1.x used the deprecated /proc/acpi/event interface to listen for
    ACPI events. In newer kernel releases that interface has been removed
    and acpid made to use netlink instead, making the check always evaluate
    to false on CentOS 7.

Checked it on CentOS 7.
It works with enabled acpi feature
