[Feature] Need a simple tool to query data in the store (e.g. for debugging/troubleshooting)

Nobody has claimed this yet.

### Willingness to contribute

No. I cannot contribute a bug fix at this time.

### Feature Request Proposal

Venice's docker image should package a simple documented tool/script to query the data

I tried using `java -jar /opt/venice/bin/venice-admin-tool-all.jar --query ..` but it returns "Schema of store: .. doesn't exist" error. This is a [documented](https://github.com/linkedin/venice/blob/main/clients/venice-admin-tool/README) way

"clients/venice-thin-client/bin/query_key.sh" (Suggested on slack) is not packaged in the docker image.

Working way is to use `java -jar /opt/venice/bin/venice-thin-client-all.jar $storeName $key $router false ""` on the venice-client

### Motivation

> #### What is the use case for this feature?

### What component(s) does this bug affect?

- [ ] `Controller`: This is the control-plane for Venice. Used to create/update/query stores and their metadata.
- [ ] `Router`: This is the stateless query-routing layer for serving read requests.
- [ ] `Server`: This is the component that persists all the store data.
- [ ] `VenicePushJob`: This is the component that pushes derived data from Hadoop to Venice backend.
- [ ] `Thin Client`: This is a stateless client users use to query Venice Router for reading store data.
- [ ] `Fast Client`: This is a stateful client users use to query Venice Server for reading store data.
- [ ] `Da Vinci Client`: This is an embedded, stateful client that materializes store data locally.
- [ ] `Samza`: This is the library users use to make nearline updates to store data.
- [X] `Admin Tool`: This is the stand-alone client used for ad-hoc operations on Venice.

Start with clients/venice-thin-client/bin/query_key.sh and the clients/venice-admin-tool/README, then inspect how the Docker image packages venice-admin-tool-all.jar and venice-thin-client-all.jar. The work is done when a documented query tool or script is included in the image and supports troubleshooting store data without relying on an external checkout.
