Check DNS entries for the network tier

EXPECTED RESULTS

Network tiers should use VPC defined DNS entries

I was able to reproduce the issue

• create vpc with DNS 8.8.8.8 and 1.1.1.1

• create vpc tier without DNS, it has DNS servers same the data center

• check the VPC VR, it uses DNSs of VPC, but VMs use VR IP and DNS of vpc tier
