[E2E Enchancement] define command line flags for different cleanup granularity

**What would you like to be added**:

Implement more command line flags for different cleanup granularity to make it more convenient for local run and debug flaky test case.

Now after running test/e2e/run_test.sh, infra like k8s, istio and Kmesh will not cleanup, but test applications will.

So add command line flag to implement such as:

- [x] Cleanup all components: this seems simple, just use kind to delete the testing k8s cluster. #649
- [ ] Don't cleanup test applications: we can use istio.test.nocleanup which is the flag of istio integration framework to control it.
And more if it's necessary.

NOTE: If there are multiple subtasks in an issue, when submitting a PR, you shoud use `fix part of #xxx` instead of directly using `fix #xxx` which will automatically close the entire issue.

Start with test/e2e/run_test.sh and inspect how the current cleanup is performed, including the istio.test.nocleanup flag and the kind-based cluster cleanup from #649. Done means command-line flags provide the requested cleanup granularity, including retaining test applications, while preserving the existing default behavior.
