[PATCH v2 21/21] avocado: Convert basic pasta tests

[David Gibson <david@gibson.dropbear.id.au>]

Convert the old-style tests for pasta (DHCP, NDP, TCP and UDP transfers)
to using avocado.  There are a few differences in what we test, but this
should generally improve coverage:

 * We run in a constructed network environment, so we no longer depend on
   the real host's networking configuration
 * We do independent setup for each individual test
 * We add explicit tests for --config-net, which we use to accelerate that
   setup for the TCP and UDP tests
 * The TCP and UDP tests now test transfers between the guest and a
   (simulated) remote site that's on a different network from the simulated
   pasta host.  This better matches the typical passt/pasta usecase
