As per deprecation notice from v11.3 release notes, and a related prior PR; this ENV is to be removed.
It's no longer considered useful, and none of the tests that configured it were actually using it for relaying anything.
## Pull Request
### ci: Run tests in parallel (part 1)
- Tests can now be arbitrarily grouped into sub-directories.
- Some tests are now run in parallel.
- CI will now spawn 4 jobs to run the whole test suite in parallel.
## Individual Commits
### tests(chore): Rename test files to serial and parallel types
- `test_helper.bats` needs more work than this PR provides to be compatible with parallel tests, so must remain as a serial test for now.
- `spam_bounced.bats` had failures as a serial test, but works well converted to a parallel test in a future commit.
### tests(CI): Adjust Makefile & GHA workflow to support new test layout
These updates support running tests that have been relocated into `serial` and `parallel/set*` directories.
- `make tests` now calls the two make targets beneath it. The only difference is that `serial` continues the "1 test at a time" approach used prior to this PR, while the `parallel` target increases the `--jobs` arg to run multiple tests concurrently (_configured by `PARALLEL_JOBS`_).
- The `test/%` target leverages Bash syntax magic to ease running single tests without providing the exact path.
- This syntax also supports providing multiple test names (eg: `make test/clamav,template`) to run.
- `**` (globstar) allows for future improvements that can group multiple test files into sub-directories by their scope (eg: anti-spam, ssl, etc).

chore: Add `shopt -s globstar` to other targets
I realized that other targets should have this as well in case it is not set.
It is better to be more explicit here than to have weird errors due to `**` not expanding properly.

fix(Makefile): Add back `.PHONY` targets
I encountered `make` telling me the target was already up-to-date, which of course is nonsense.
I therefore added back the `.PHONY` targets to ensure tests are always run.

docs: Added instructions for running a single test

### tests(chore): Use `REPOSITORY_ROOT` export var from Makefile
Allows for using `load` with an absolute path instead of a relative one, which makes it possible to group tests into different directories.
Parallel tests differ slightly, loading the newer `helper/common.bash` and `helper/setup.bash` files instead of the older `test_helper/common.bash` which serial tests continue to use.
### tests(refactor): `common.bash` helper split into two files
The current `test/test_helper/common.bash` was getting large. Setup logic has been extracted out into a new file.
`common.bash` resides in a directory named `test_helper/`, the `test_` prefix is redundant.
As an interim solution this provides a new approach for the updated tests, while the "old" tests can use the "old" `common.bash`. Eventually all tests should migrate to the new approach in `helper/` instead of the older `test_helper/`.
The new helper files are located under `test/helper/` (_which drops the `test_` prefix_). The new and updated helpers apply the new naming convention for ENV variables (_such as `CONTAINER_NAME` or `IMAGE_NAME`_).
---
Some refactoring occurred, including new methods like `_run_in_container()` and `_default_teardown()`.
---
I encountered a situation before in which the updated tests would fail because there were collisions of ENV names in the tests (_for example with `CONTAINER_NAME`_).
### tests(refactor): Conversion to parallel tests and use revised helpers
- Introduced `CONTAINER_NAME` and `TEST_NAME_PREFIX` as new vars for better managing test consistency (DRY).
- `CONTAINER_NAME` replaces any repeated container name with the variable. The value will differ slightly as the prior prefix (`mail_`) has been changed to `dms-test-`.
- `TEST_NAME_PREFIX` provides a prefix value for each `@test` description string.

Currently a change detection would be triggered and during processing, a CRLF is converted to LF, which updates the `postfix-accounts.cf` file and triggers another change event.
No need for the first approach to add an account, and it is the culprit for causing the CRLF to appear.
