Huan Xie 26edd7b071 Install conntrack in XenServer Dom0
Neutron openvswitch agent running in compute node will control the
actual connection of the VMs in Dom0 via conntrack-tools, but Dom0
doesn't install conntrack-tools RPM by default.
This patch is to add such support with XenServer 7.0 and above.
