nixos/test-driver: undeprecate create_machine 
This warning was added a year and a half ago, but still no test in
NixOS directly instantiates the machine class, presumably because it's
not actually possible for a test to do so without losing
functionality.  For example, there's no way for a NixOS test to access
the output directory that create_machine passes to the Machine
constructor.

This warning is therefore just contributing to alert fatigue for
users, who are unable to follow its advice.  Once it's actually
possible to do what it suggests, the warning can be reintroduced.

nixos/test-driver: highlight driver log lines 
There is a whole lot of noise in a NixOS test log due to journal,
commands, and test driver messages all being mixing together.
With this commit the test driver messages are highlighted so you don't
have to squint too much to see where a subtest starts and ends or what
was the last command being run.

Here's an excerpt from a highlighted log:

nixos/test-driver: deduplicate VLANs 
Naively deduplicate VLANs in the python driver for NixOS tests. The
current implementation accidentally works, since the VLan class mutates
the environment. On construction it sets QEMU_VDE_SOCKET_${id} and this
environment variable gets overwritten once a second VLAN with the same
id is constructed. Because the NIC flags passed to qemu just use the
QEMU_VDE_SOCKET_${id} environment variable, this implicitly chooses a
single vde_switch process for each VLAN.

However, this leads to unusable vde_switch processes being spawned in
each test run and as a side effect makes it impossible to access the
correct VLan objects in the interactive test driver. It also makes it
remarkably hard to understand why the current implementation ever
worked.
