ctdb-tests: Try to handle IPv6 addresses for local daemons

Browse Source 
If CTDB_USE_IPV6 is set then use IPv6 addresses for nodes and public
IPs.  This can be useful for some simple tests.  However, the node
address actually needs to be on lo so that ctdbd can bind to the port
on that address, so they actually need to be added as root before
running tests, like this:

  for i in $(seq 1 10) ; do ip addr add "fc00:10::${i}/64" dev lo ; done

IPv4 127.0.0.0/8 addresses are somehow magic and only one needs to be
on lo so that many can be bound to.

Also change the IPv4 node addresses to be (slightly) more exotic.

For both IPv4 and IPv6, choose addresses that are compatible with
socket wrapper.
