Description: Test to validate metadata service on VM creation.
1.Verify from global-vrouter-config if metadata configures or not - fails otherwise
2.Create a shell script which writes 'hello world ' in a file in /tmp and save the script on the nova api node
3.Create a vm with userdata pointing to that script - script should get executed during vm boot up
4.Go to the vm and verify if the file with 'hello world ' written saved in /tmp of the vm - fails otherwise

Description: Validate Ping between 2 VMs in the same VN, 2 VMs in different VN
subnets.
Test steps:
1. Create 1 IPAM's.
2. Create 1 VN with 2 subnets and launch 2 VMs in them.
3. Ping between the VMs in the same VN should go thru fine.
4. Ping to the subnet broadcast and all-broadcast address.
Pass criteria: VM in the same subnet will respond to both the pings, while the VM in a different VN should respond only to the
all-broadcast address.
