- updated `tests/TESTING.md`
- cgroup, snapshotter, and install tests all under tests/vagrant
- cgroup and snapshotter workflows trigger for all code changes on all branches (excluding markdown docs, install script, and other vagrant tests)
- install workflow triggers for relevant script and fixture changes, only on master or pull-requests that target it
- integration and unit test workflows should not trigger for install script changes nor anything under tests/vagrant

Problem:
Before, to customize CoreDNS, one had to edit the default configmap,
which gets re-written on every K3s server restart.

Solution:
Mount an additional coredns-custom configmap into the CoreDNS container
and import overrides and additional server blocks from the included
files.

Since we now start the server's agent sooner and in the background, we
may need to wait longer than 30 seconds for the apiserver to become
ready on downstream projects such as RKE2.

Since this essentially just serves as an analogue for the server's
apiReady channel, there's little danger in setting it to something
relatively high.

Leverage posix builtins + grep (with regex matching) to emit quoted
environment variables to K3S_FILE_ENV, e.g.:

```shell
$ export CONTAINERD_TEST_1='one!1' K3S_TEST_2=two K3S_TEST_3='thr ee' TEST_4='!@#$%^&*()_+four!'
$ sh -c export | while read x v; do echo $v; done | grep -E '^(K3S|CONTAINERD)_'
CONTAINERD_TEST_1='one!1'
K3S_TEST_2='two'
K3S_TEST_3='thr ee'
