Previously this built the binaries for every distro. This is a bit
overkill given we are using static binaries. This patch makes us only
build once.
There was also a weird issue with how processes were being managed.
Previously we just killed qemu with Process.Kill(), however that was
leaving behind zombies. This has been mended to not only kill qemu but
also waitpid() the process so it doesn't become a zombie.

The OpenSUSE 15.1 image we are using (and conseqentially the only one
that is really available easily given it is EOL) has cloud-init
hardcoded to use the OpenStack metadata thingy. Other OpenSUSE Leap
images function fine with the NoCloud backend, but this one seems to
just not work with it. No bother, we can just pretend to be OpenStack.
Thanks to Okami for giving me an example OpenStack configuration seed
image.

Arch is a bit of a weirder distro, however as a side effect it is much
more of a systemd purist experience. Adding it to our test suite will
make sure that we are working in the systemd happy path.

This distro is about to be released. OpenSUSE has historically had the
least coverage for functional testing, so this may prove useful in the
future.

Instead of testing all the VMs at once when they are all ready, this
patch changes the testing logic so that the vms are tested as soon as
they register with testcontrol. Also limit the amount of VM ram used at
once with the `-ram-limit` flag. That uses a semaphore to guard resource
use.
Also document CentOS' sins.

If you set `-distro-regex` to match a subset of distros, only those
distros will be tested. Ex:
$ go test -run-vm-tests -distro-regex='opensuse'

Don't try to do heuristics on the name. Use the net/interfaces package
which we already have to do this sort of stuff.

Instead of pulling packages from pkgs.tailscale.com, we should use the
tailscale binaries that are local to this git commit. This exposes a bit
of the integration testing stack in order to copy the binaries
correctly.
This commit also bumps our version of github.com/pkg/sftp to the latest
commit.
If you run into trouble with yaml, be sure to check out the
commented-out alpine linux image complete with instructions on how to
use it.

Previously we spewed a lot of output to stdout and stderr, even when
`-v` wasn't set. This is sub-optimal for various reasons. This patch
shunts that output to test logs so it only shows up when `-v` is set.

Instead of relying on a libvirtd bridge address that you probably won't
have on your system.

This will spin up a few vms and then try and make them connect to a
testcontrol server.
