Migrate cli-related CI to E2E test

[zhzhuang-zju]

What would you like to be added:

Thank you to @luyb177 for the contribution. We have completed the module for e2e testing of the karmadactl init functionality in #6728. Currently, it supports testing the installation capability of karmadactl init in e2e. The tests for CI Test on Kubernetes and CI init with config file can now be migrated to the e2e module, so we are issuing the following tasks.

• migrate CI Test on Kubernetes
• migrate CI init with config file
• deprecate hack script cli-testing-environment.sh
• deprecate hack script cli-testing-init-with-config.sh

Note: Tasks 3 and 4 should only be carried out after tasks 1 and 2 are completed.

@rayo1uo Thank you for your active participation. This task is still under analysis and breakdown. You can wait for me to complete a demo before proceeding with the next steps. Of course, if you have already completed a part of it, we can arrange the next step according to your progress.

@zhzhuang-zju Thanks! I'll wait for the demo to be ready so I can submit commits that meet the requirements as much as possible.

@zhzhuang-zju Hi there! It looks like I can begin working on this issue. Should I primarily refer to PR #6928?

[zhzhuang-zju]

Great to hear from you!

In fact, we still need to wait for PR #6928 to be merged first. Once it’s merged, you can add an e2e test for karmadactl init that installs a Karmada instance using a configuration file.

Btw, you're welcome to review #6928 and help move this task forward—thank you!
