TestNetworkMachineCNIWithParsedConfig is failing against ARM

[vvejell1]

When trying to run an ARM integration test against the Firecracker-Go SDK, we must execute testPing in TestNetworkMachineCNIWithParsedConfig in order to verify that the network is functioning properly and that the machine is up by sending a number of pings through various virtual machines. While running this test with 1-3 VMs produces inconsistent results, but not all pings will always be successful. It appears that there is a gateway problem, as the Destination Host is not reachable. As a result, I'm trying to block or skip the 'testPing,' which is not supported by ARM. I found that the TestNetworkMachineCNIWithParsedConfig test can be passed when the "testPing" is skipped.
