[FEATURE] Add support for OLTP telemetry

[chatton]

Problem to solve

In order to gain more insight into the system, we should add the capability to trace traffic between components.

Proposed solution or feature

Add support via the otlp go library

• Add tracing to the executor
• Inject W3C headers for the Engine JSON-RPC (to allow for tracing between ev-node -> ev-reth )
• Add tracing to DA client
• Identify any additional components that would benefit from tracing.
