Our CI tests on RHEL and Fedora and we want to test the systemd cgroup
driver. However, kubelet needs to run in tests with systemd cgroup
driver as well, or tests fail. This patch fixes broken CI because of
not matching cgroup driver between CRI-O and the kubelet.

Because we need a working CNI plugin to setup a correct netns so
sandbox_run can grab a working IP address.

Add new directory /etc/crio/hooks.d, where packagers can drop a json config
file to specify a hook.
The json must specify a valid executable to run.
The json must also specify which stage(s) to run the hook:
prestart, poststart, poststop
The json must specify under which criteria the hook should be launched
If the container HasBindMounts
If the container cmd matches a list of regular expressions
If the containers annotations matches a list of regular expressions.
If any of these match the the hook will be launched.

Without any swap space enabled, it's possible some intensive operation
can chew up all the memory on the test VM. Enabling swap space will
prevent this for minor cases, but could lead to disk-thrashing if the
memory demand is excessive.
Since the test system never reboots, using a file-backed swap should
suffice. Though not ideal, it's easy to setup and doesn't require any
interactions with the cloud that owns the VM or the job that created it.
