Wait for ipv6 addrs when launching nodes

Browse Source 
When launching new nodes with launch-node.py we need to wait for ipv6
addresses to configure prior to running ping6 sanity checks. The reason
for this is some clouds rely on router advertisements to configure ipv6
addrs on VMs. These happen periodically and the VM may not have its ipv6
address configured yet when we try to ping6 otherwise.
