Add support for KIP-714

[mimaison]

Since Kafka 3.7.0, with KIP-714 MetricsReporter implementations can also implement the ClientTelemetry interface to gather metrics from Kafka clients.

I guess that should have a wider proposal about how would it work and what would be the benefits.

In order to implement #55 properly, I realized it made more sense to split the reporter into a client and a server module. #55 and this this issue are server only features so having different modules would simplify the reporter logic. My plan is to open a new proposal for that refactoring (this would change class names and dependencies) and it should cover this issue as well.

TBH, I'm not sure how KIP-714 relates to splitting the reporter into a client and server modules. You can split that even without involving anything from KIP-714, or? And even if we would want to support KIP-714, the client part would still need to expose the metrics separately as well because not everyone would want to use KIP-714.

Triaged on 23.1.2025: @mimaison is going to have two proposals for this. One related to the splitting into client and server modules and the other one for supporting KIP-714.
