e2e tests need a ping6 test for IPv6-only clusters

Browse Source 
e2e tests provide only an (IPv4) ping test for external connectivity.

We need a way to conditionally run a ping6 external connectivity check,
and disable the (IPv4) ping-based external connectivity check,
for end-to-end testing on IPv6-only clusters.

This feature will be needed for creating gating IPv6 CI tests.
