This is a bit opinionated, but some comments in integration tests do not
really help to understand the nature of the tests being performed by
stating something very obvious, like
# run busybox detached
runc run -d busybox
To make things worse, these not-so-helpful messages are being
copy/pasted over and over, and that is the main reason to remove them.

Currently only amd64 and arm64v8 tarball have been checked in testdata,
while busybox bundle is downloaded on fly, and supports multiple architectures.
To enable integration tests for more architectures, the hello world
bundle is replaced by busybox one.

In order to make 'runc --debug' actually useful for debugging nsexec
bugs, provide information about all the internal operations when in
debug mode.

First, add runc --debug exec test cases, very similar to those in
debug.bats but for runc exec (rather than runc run). Do not include json
tests as it is already tested in debug.bats.
Second, add logrus debug to late stages of runc init, and amend the
integration tests to check for those messages. This serves two purposes:
- demonstrate that runc init can be amended with debug logrus which is
properly forwarded to and logged by the parent runc create/run/exec;
- improve the chances to catch the race fixed by the previous commit.

1. Remove redundant "echo $output" from the first test case, as "runc"
helper function already logs the output.
2. Show the contents of log.out to stderr, so it case of error we can
see what is going on.
3. Remove the check that `log.out` file exists. This check is redundant,
since right after it we do `cat log.out` and check its exit code.
4. Factor out common checks into check_debug.

1. Get rid of fixed ROOT, *_BUNDLE, and CONSOLE_SOCKET dirs.
Now they are temporary directories created in setup_bundle.
2. Automate containers cleanup: instead of having to specify all
containers to be removed, list and destroy everything (which is
now possible since every test case has its own unique root).
3. Randomize cgroup paths so two tests running in parallel won't
use the same cgroup.
Now it's theoretically possible to execute tests in parallel.
Practically it's not possible yet because bats uses GNU parallel,
which do not provide a terminal for whatever it executes, and
many runc tests (all those that run containers with terminal:
true) needs a tty. This may possibly be addressed later.

Bats' run should only be used when we want to check both the command
output and its non-zero exit status.
Otherwise, we can rely on implicit exit code check (as the tests are
run with set -e), or use if, etc.

Various bats tests use various types of indentation (about half
is tabs, the rest is 2 spaces, 4 spaces, etc.).
Let's bring it to one style (tabs) using recently added
shfmt support for bats files (see [1]).
This commit is brought to you by
shfmt -ln bats -w tests/integration/*.bats

This makes it much simpler to write tests, and you don't have to worry
about some of the oddness with bats.
