Bence Romsics 080770cd7b Suppress IPv6 metadata DAD failure and delete address ... IPv4 DAD is non-existent in Linux or its failure is silent, so we never needed to catch and ignore it. On the other hand IPv6 DAD failure is explicit, hence comes this change. This of course leaves the metadata service dead on hosts where duplicate address detection failed. But if we catch the DADFailed exception and delete the address, at least other functions of the dhcp-agent should not be affected. With this the IPv6 isolated metadata service is not redundant, which is the best we can do without a redesign. Also document the promised service level of isolated metadata. Added additional tests for the metadata driver as well.
