What does the enhancement do?

The greptimedb ecosystem is growing rapidly and may bring unexpected behaviors for downstream software, such as SDKs, greptimedb-operator, gtctl, etc. To resolve the problem, we need to add the weekly CI to run functionality regression testing based on the latest weekly release artifacts.

The test cases should cover most scenarios that are described in docs.

Implementation challenges

It's the big job of writing multiple test cases! I will create multiple tasks to track these issues, which may be growing:

• Add the CI skeleton to run the functionality regression testing periodically. Each test case should be the standalone CI job;
• Basic operations of binaries and images;
• SDKs tests: ci: run sdk tests for weekly build #2579;
• Deployment tests(K8s operator,helm charts, gtctl);
