[ipv6] Regarding 8220673: Add test library support for determining platform IP support

[Chris Hegarty]

Arthur,

Several tests require the presence of either: 1) IPv4, or 2) IPv6, or
3) IPv4&IPv6. A test library utility class could provide such.

Here is a rough idea about how to determine Internet Protocol support.

It might be enough to experiment with and see how far it gets us?

P.S. Let's use the `[ipv6]` subject prefix to track related work
