Adding a workaround for enabling steering in ConnectX-3 devices

This file will add this configuration
"options mlx4_core log_num_mgm_entry_size=-1" to
/etc/modprobe.d/mlx4.conf file in order to enable steering in
ConnectX-3 devices and then will rebuild the initramfs at the first
boot stage

# This means get_resource from the parent template will get the userdata, see:
# http://docs.openstack.org/developer/heat/template_guide/composition.html#making-your-template-resource-more-transparent
# Note this is new-for-kilo, an alternative is returning a value then using
# get_attr in the parent template instead.
