* chore: Extract out Dovecot Quota test cases into new test file
Test cases are just cut + paste, no logic changed there yet.
* chore: Rename test case descriptions
* chore: Use `setup ...` methods instead of direct calls
* chore: Adjust `_run_in_container_bash` to `_run_in_container`
Plus some additional bug fixes in the disabled test case
* tests(refactor): Revise ENV test cases for max mailbox and message sizes
* tests(refactor): Revise ENV test cases for mailbox and message limits v2
Removes the extra variables and filtering in favour of explicit values instead of matching for comparison.
- Easier at a glance to know what is actually expected.
- Additionally reworks the quota limit checks in other test cases. Using a different formatter for `doveadm` is easier to match the desired value (`Limit`).
* chore: Sync improvement from `tests.bats` master
