This adds a pair of tests, one which does almost all the work
from the test case, the other just a client test to check that
we can connect to an HTTP server running in a container on the
host. We also have to bump the _console_wait_login timeout on
this path a bit as we're booting a disk image that was installed
with DHCP working, but we change the network setup so DHCP does
not work any more, and the system spends quite some time trying
to bring the network up on boot before eventually giving up and
proceeding.
