Need a tool for collecting TiDB operator related information for analysis

Feature Request

Is your feature request related to a problem? Please describe:

For on-prem workloads, sometimes we need to collect information related to tidb-operator and hand it to the SRE team for further analysis. It would be nice to have a tool to automate the procedures.

Describe the feature you'd like:

It would be nice if tidb-operator could provide a binary that can help collect related information in the cluster with simple configurations.

Describe alternatives you've considered:

We can ask the SRE team to run kubectl manually to collect information, but it's error-prone and might need multiple rounds of communication to collect the information we need. We can also deliver a script to automate this, but it might be difficult to customize.

Teachability, Documentation, Adoption, Migration Strategy:

Given the binary and a kubeconfig for the cluster, users can simply run the binary to collect the info they need, and export it to maybe a zip bundle. Users can use a config file to config the information they want to collect, e.g. they can specify the namespace to collect information.

No source files, entry points, or tests are named. Start by reviewing the repository structure and existing kubectl-based operational workflows to determine where a collection tool would belong. Define the configuration, collected information, output bundle, and validation criteria with maintainers before implementation.
