Could not find init script or upstart conf file for 'libvirt-bin'

On MOS 7.0 with LMA 0.7, puppet failed to apply lma_collector-0.7/puppet/manifests/compute.pp with the following error:

# puppet apply --debug --modulepath=/etc/fuel/plugins/lma_collector-0.7/puppet/modules /etc/fuel/plugins/lma_collector-0.7/puppet/manifests/compute.pp
[...]
Error: /Stage[main]/Lma_collector::Logs::Libvirt/Service[libvirt-bin]: Could not evaluate: Could not find init script or upstart conf file for 'libvirt-bin'

It occurs because in MOS 7.0 the version of libvirt is 1.2.9-9~u14.04+mos2 that is build for mos7.0 and in this version the file /etc/init.d/libvirt-bin that is expected by puppet manifest has been renamed in /etc/init.d/libvirtd.

To fix the problem we need to check which file is available (/etc/init.d/libvirt-bin or /etc/init.d/libvirtd). Maybe the cleanest way is to do a fact that exposes this and use it in lma_collector-0.7/puppet/modules/lma_collector/manifests/logs/libvirt.pp for setting $libvirt_service.
