Feature Request

As discussed here it would be cool to provide a way for a data plane to register itself into the available data plane instances.

Which Areas Would Be Affected?

Data Plane Selector, DPF

Why Is the Feature Desired?

In use cases where elasticity of data planes matters this could help spinning new data planes without the efforts manually maintaining all the data plane instances available.

Solution Proposal

We could write a new extensions that self register itself using the selector api based on a configuration.

If we support self registration we should also support de-registration if the instance
is not available. Probably we could have some sort of heartbeat mechanism that ensure that the registered instances are up and running.
