Provide a gRPC endpoint to getting the version

[LinuxSuRen]

Currently, we only have one endpoint for running the test cases. The VS Code extension could communicate with it. It would be great if the VS Code side could get the version and prompt users if they upgrade atest according to the version comparison.

Please feel free to read the following references before trying to fix this issue:

I found out that this feature already exists. So we only need to let the vs-code extension to call it.
