feat(metrics): implement metric-gathering capabilities for seed nodes

[bsodmike]

This is a draft - Please do not review (yet).

This PR adds a new node type called a Metrics Node. This will serve as a foundational piece for further development and integration within this framework.

• [x] Introduce a new config parameter, "i_am_metric": true, to denote its additional metric-gathering capabilities.
• [x] Add baseline tests to detect if the seed node has metric gathering capabilities.
• [ ] The Metrics Node should collect data on executed swaps. Specifically, it should prepare hourly candlestick data representing the price graph of a coin in the DeFi Framework, providing data with more detailed granularity, such as every 15 minutes or every 4 hours.
• [ ] The implementation of the Metrics Node itself must be native-target only, similar to stats_swaps.
• [ ] Complete tests for metrics gathering (as per above)
• [x] Implement a new RPC method in the dispatcher to handle requests for the data collected by the Metrics Node.
• [ ] Wire RPC method
• [ ] Ensure that the RPC method that requests data from this Metrics Node should work seamlessly across all nodes, wasm or native.

Important considerations

• Efficiently handle data storage, processing, and caching to quickly allow for data retrieval.
