DPDK HQoS: enable vpp control plane thread connection to hqos thread

Browse Source 
The vpp control plane thread generates different types of packets such as ARP,
DHCP client, IPv6 RA, etc. which need to go through HQoS thread associated
with the output interfaces. Therefore, this patch enables vpp main thread
connection with the HQoS thread through dedicated SWQ.
