[Dynamic Protocol State | M3] Metrics and telemetry for KV store

[durkmurder]

Context

To get more insight on how protocol operates and collect some statistics as well as implement some alerts we would like to implement and collect metrics. Introduce an interface that can be used to report invalid service events and [maybe] state changes to the protocol state. Expect to expand this interface in future. Connect it with reporting system.

Definition of Done

• Implement an interface to report telemetry and/or metrics.
• Connect telemetry and/or metrics with handlers.
