feat: test integration connection (#669)

* feat: add test integration for pi-hole * refactor: test integration for pi-hole * fix: multiple secrets of same type could be used for integration creation * fix: remove integration test connection test and add mock for test-connection function * fix: add missing onUpdateFn to mysql integration secrets * fix: format issues * feat: add home assistant test connection * fix: deepsource issues * test: add system integration tests for test connection * fix: add before all for pulling home assistant image * test: add unit tests for handleTestConnectionResponseAsync * test: add unit test for testConnectionAsync * test: add mroe tests to integration-test-connection * fix: deepsource issues * fix: deepsource issue * chore: address pull request feedback
