Merge pull request juju#18834 from anvial/ignore-error-on-teardown-ci

juju#18834

This change helps to ignore CI pipeline failures due to teardown issues until the clean-up infrastructure is fixed.

- Updated `destroy_controller()` to handle errors during teardown gracefully.
- Ensured that the test suite continues execution even if teardown fails.



```sh
# we can check on any test, that will create and destroy controller/model
cd tests
./main.sh -v actions run_actions_params
```
