Configure the numvfs for SRIOV interfaces

This patch shall create VFs via the PCI SYS interface.
Default value : $::os_service_default
Sample Format : ['eth0:4','eth2:128']
For values as in sample format, the sriov_numvfs config files
for eth0 and eth2 will have the values 4 and 128 respectively
The SR-IOV numvfs configuration shall be persisted in /sbin/ifup-local
so that, during the bootup of the compute nodes, the numvfs
configuration will be restored.
