Fix CloudDnsWriter glue record A/AAAA arguments

Browse source 
Previously, CloudDnsWriter used InetAddress.toString() to produce the ipv4/6
address string (i.e. 127.0.0.1 or 0:0:0:0:0:0:0:1) used as an argument to the
Cloud DNS API. However, this fails because InetAddress uses the format
"HostName/IpAddress" for toString(), which uses the empty string as a HostName
if unspecified. This resulted in the erroneous use of a prefix slash (i.e.
"/127.0.01") as an InetAddress argument, causing all glue record updates to
fail.

This change replaces InetAddress.toString() with InetAddress.getHostAddress(),
which properly generates the IP address for the InetAddress. This also replaces
a lot of logic in the corresponding test with concrete equivalents, preventing
obvious errors like this from creeping up on us in the future.
