Rename StringNetworkSpecifier to Ethernet

Tests just need a specifier to verify general NetworkSpecifier
functionality. They can use EthernetNetworkSpecifier the same way they
use StringNetworkSpecifier.

To keep the tests passing on Q and R, add a CompatUtil class that will
keep creating StringNetworkSpecifiers (now removed) instead.
