Add an info endpoint on control plane

[ddieruf]

Can the control plane have an additional endpoint maybe at /info where it provides details about the installation?

• Versions of the services
• number of replicas
• Status

And if it's possible a list of available agents. I know that agents are pre-installed but hard coding agent info in downstream tooling from the control plane doesn't seem like a good idea. It would be better to discover available agents.

I think that adding an endpoint to discover available agents is a great idea. Together with it we need a way to write docs for each agent directly into the code, and that also combines with a better validation at deployment time.
