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.

Only minimal tailscale + tailscaled for now.
And a super minimal in-memory logcatcher.
No control ... yet.
