refactor: Reorganise integration tests (#9282)

This commit reorganises cli/tests/integration_tests.rs.

All integration tests had been moved into integration module,
which allows to run only integration tests by "cargo test integration".

Additionally some tests were further grouped under nested modules
like "inspector", "file_watcher" or "repl".
